TPS54560BDDAR Equivalent & Substitute Parts

Part Overview

The TPS54560BDDAR is an active, production-status buck switching regulator IC from Texas Instruments, designed for step-down voltage conversion applications. It delivers adjustable positive output from 0.8V to 58.8V with 5A output current capability, operating across a 4.5V to 60V input range. The device is housed in an 8-PowerSOIC package and features Eco-Mode operation for efficiency optimization. Finding equivalent substitute parts is necessary when addressing supply chain constraints, packaging preferences, or specific application requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS54560BDDAR is determined by the following critical parameters:

• Topology & Function: Buck switching regulator with step-down capability
• Output Configuration: Positive adjustable output
• Output Voltage Range: Minimum 0.8V, maximum ≥58.8V
• Input Voltage Range: Minimum ≤4.5V, maximum ≥60V
• Output Current: 5A capability
• Mounting Type: Surface mount
• Compliance: ROHS3 compliant, active product status

The RT6365GQW meets these substitution criteria across all critical electrical parameters while offering alternative packaging and switching frequency characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS54560BDDAR and RT6365GQW are active, production-status devices with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

TPS54560BDDAR is preferred when the 8-PowerSOIC package footprint is required or when fixed 500kHz switching frequency is specified in the design.

RT6365GQW is suitable as a substitute when the 10-WDFN package is acceptable, when lower input voltage minimum (4V vs 4.5V) provides design margin, or when programmable switching frequency (100kHz to 2.5MHz) offers system-level optimization benefits. The RT6365GQW provides slightly higher maximum output voltage (60V vs 58.8V).

Both devices maintain identical output current (5A), adjustable output configuration, and operating temperature range, ensuring functional compatibility in step-down buck regulator applications.

Frequently Asked Questions (FAQ)

Q: Can RT6365GQW directly replace TPS54560BDDAR in existing designs?

A: Electrical substitution is valid based on matching output current (5A), adjustable output voltage range (0.8V minimum), and input voltage specifications (4.5V to 60V). However, the package change from 8-PowerSOIC to 10-WDFN requires PCB layout redesign. Verify that the 10-WDFN footprint accommodates your board space constraints.

Q: What are the key differences between these parts?

A: The primary differences are package type (8-PowerSOIC vs 10-WDFN), switching frequency (fixed 500kHz vs programmable 100kHz to 2.5MHz), and input voltage minimum (4.5V vs 4V). Electrical performance and output specifications remain equivalent.

Q: Are both parts suitable for the same temperature range?

A: Yes. Both devices operate across -40°C to 150°C junction temperature, ensuring compatibility in equivalent thermal environments.

Q: What compliance certifications apply to both parts?

A: Both TPS54560BDDAR and RT6365GQW are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001.

Q: Does the switching frequency difference affect substitution suitability?

A: The RT6365GQW offers programmable switching frequency (100kHz to 2.5MHz) versus the fixed 500kHz of TPS54560BDDAR. This allows system-level optimization but requires verification that your application's EMI filtering and component ratings accommodate the frequency range.
