TPS565247DRLR Equivalent & Substitute Parts

Part Overview

The TPS565247DRLR is an active buck switching regulator IC manufactured by Texas Instruments, classified as a Power Management Integrated Circuit (PMIC). This device functions as a step-down converter with positive adjustable output, delivering up to 6A output current across a single output channel. The regulator operates across an input voltage range of 3V to 16V and supports adjustable output voltage from 0.6V to 7V, making it suitable for diverse power supply applications requiring regulated DC conversion.

The TPS565247DRLR is currently in active product status with 3100 units available in inventory. Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, or address specific application requirements such as thermal operating range, package form factor, or output current capacity constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS565247DRLR with alternative buck regulator ICs is determined by alignment across the following critical parameters:

Functional Compatibility Requirements:

• Topology: Buck (step-down) switching regulator
• Output Configuration: Positive adjustable output
• Number of Outputs: Single output channel
• Synchronous Rectifier: Integrated synchronous rectification

Electrical Operating Range Compatibility:

• Input Voltage Range: Minimum 3V to 16V maximum
• Output Voltage Range: Adjustable from 0.6V minimum to 7V maximum
• Output Current Capacity: Minimum 6A sustained current delivery
• Switching Frequency: 600kHz nominal operation

Physical and Environmental Constraints:

• Mounting Type: Surface mount technology
• Operating Temperature Range: -40°C to 125°C junction temperature
• Package Form Factor: SOT-563 or SOT-666 footprint compatibility

Substitute parts must satisfy all functional topology requirements, support the specified input and output voltage ranges, deliver the required output current capacity, and operate within the defined temperature range. Package compatibility and thermal specifications are secondary selection criteria when primary electrical parameters align.

Engineering Selection Recommendations

Primary Selection Criteria:

The TPS565247DRLR remains the primary component choice for applications requiring the full specified performance envelope. This device delivers 6A output current capacity, supports output voltage adjustment to 7V maximum, and operates reliably at junction temperatures up to 125°C. The SOT-563/SOT-666 package provides a compact form factor suitable for space-constrained designs.

Substitute Selection Conditions:

The RT6255AHGJ6F substitute part is applicable under the following conditions:

1. Output Current Requirement: Applications requiring maximum sustained output current of 5A or less. Designs demanding the full 6A capacity of the TPS565247DRLR cannot use this substitute without thermal or current-limiting design modifications.

2. Output Voltage Requirement: Applications with maximum output voltage requirements of 5V or less. Designs requiring adjustable output voltage above 5V cannot use this substitute.

3. Input Voltage Range: Applications operating within the 4.5V to 18V input range. Designs requiring input voltage operation below 4.5V cannot use this substitute.

4. Thermal Operating Range: Applications operating at ambient temperatures of 85°C or below. Designs requiring junction temperature operation above 85°C cannot use this substitute.

5. Package Compatibility: PCB layouts must accommodate the TSOT-23-6 (SOT-23-6 Thin) footprint. Direct footprint substitution with SOT-563/SOT-666 is not possible without PCB redesign.

6. Compliance Requirements: The RT6255AHGJ6F meets ROHS3 compliance and REACH unaffected status, suitable for applications with regulatory compliance mandates.

Both devices are active products with established supply availability. Selection between these parts depends on application-specific electrical requirements and physical constraints rather than product lifecycle status.

Frequently Asked Questions (FAQ)

Q: Can the RT6255AHGJ6F substitute for the TPS565247DRLR in all applications?

A: No. The RT6255AHGJ6F has three limiting factors: maximum output current of 5A (versus 6A), maximum output voltage of 5V (versus 7V), and maximum operating temperature of 85°C (versus 125°C junction temperature). Substitution is valid only when application requirements fall within these lower limits.

Q: What is the impact of the different switching frequencies (600kHz vs. 500kHz)?

A: The TPS565247DRLR operates at 600kHz while the RT6255AHGJ6F operates at 500kHz. Higher switching frequency typically results in smaller passive component values and reduced output ripple voltage. Applications sensitive to switching frequency harmonics or requiring specific EMI filtering characteristics should account for this 100kHz difference.

Q: Are the package footprints interchangeable?

A: No. The TPS565247DRLR uses SOT-563 or SOT-666 packages, while the RT6255AHGJ6F uses TSOT-23-6 (SOT-23-6 Thin). These are physically different footprints requiring separate PCB layouts. Direct board-level substitution without PCB redesign is not possible.

Q: What does the Moisture Sensitivity Level (MSL) difference mean?

A: The TPS565247DRLR has MSL 1 (unlimited moisture tolerance), while the RT6255AHGJ6F has MSL 3 (168-hour tolerance). MSL 3 components require controlled storage conditions and have a limited shelf life after moisture exposure. For applications with extended storage or high-humidity environments, the TPS565247DRLR offers superior reliability.

Q: Can I use the RT6255AHGJ6F if my application requires 6A output current?

A: No. The RT6255AHGJ6F is rated for maximum 5A continuous output current. Using this device in a 6A application will cause thermal stress, reduced efficiency, and potential device failure. The TPS565247DRLR must be used for 6A applications.

Q: What is the significance of the different input voltage minimums (3V vs. 4.5V)?

A: The TPS565247DRLR operates with input voltage as low as 3V, while the RT6255AHGJ6F requires minimum 4.5V input. Applications powered by 3V to 4.4V sources cannot use the RT6255AHGJ6F substitute. The TPS565247DRLR is required for low-voltage input applications.

Q: Are both devices suitable for automotive or industrial temperature ranges?

A: The TPS565247DRLR supports -40°C to 125°C junction temperature operation, suitable for extended industrial and automotive applications. The RT6255AHGJ6F supports -40°C to 85°C ambient temperature operation, limiting its use to commercial and light industrial environments. For high-temperature applications, the TPS565247DRLR is the appropriate choice.

Q: What compliance certifications should I consider when selecting between these parts?

A: The RT6255AHGJ6F is ROHS3 compliant and REACH unaffected. The TPS565247DRLR RoHS status is listed as not applicable. For applications requiring RoHS3 compliance certification, the RT6255AHGJ6F meets this requirement. Both devices carry EAR99 ECCN classification and 8542.39.0001 HTSUS code.
