AP4460AEN Equivalent & Substitute Parts

Part Overview

The AP4460AEN is a boost switching regulator IC manufactured by Asahi Kasei Microdevices (AKM). This positive adjustable step-up converter is designed for applications requiring voltage regulation from a low input voltage to a higher adjustable output. The device features a synchronous rectifier and operates across a wide temperature range of -30°C to 85°C.

The AP4460AEN is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure design continuity and maintain supply chain reliability for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP4460AEN is determined by the following critical parameters:

• Topology: Boost (step-up) switching regulator configuration
• Output Configuration: Positive adjustable output
• Number of Outputs: Single output
• Synchronous Rectifier: Presence of integrated synchronous rectification
• Input Voltage Range: Compatibility with 0.14V to 4V input
• Output Voltage Range: Adjustable output from 2.5V to 4V
• Mounting Type: Surface mount technology
• Operating Temperature Range: -30°C to 85°C minimum requirement

The TPS61200DRCR from Texas Instruments meets these core functional requirements as a boost switching regulator with positive adjustable output, single output configuration, and integrated synchronous rectification. Both devices operate as step-up converters suitable for low-voltage input applications.

Parameter Comparison

Engineering Selection Recommendations

The TPS61200DRCR is an active product from Texas Instruments, providing supply chain continuity for applications currently using the obsolete AP4460AEN. Both devices share the core functional architecture of boost switching regulators with positive adjustable outputs and integrated synchronous rectification.

The TPS61200DRCR offers an extended input voltage range (0.3V to 5.5V) compared to the AP4460AEN (0.14V to 4V), and a lower minimum output voltage (1.8V versus 2.5V). The TPS61200DRCR operates across a wider temperature range (-40°C to 85°C) and maintains the same MSL rating of 2 (1 Year).

Package differences exist: the AP4460AEN uses a 24-QFN (4x4) footprint, while the TPS61200DRCR uses a 10-VSON (3x3) footprint. PCB layout modifications are required for physical substitution.

Both devices comply with RoHS and REACH standards where applicable. The TPS61200DRCR is RoHS3 compliant and REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can the TPS61200DRCR directly replace the AP4460AEN without PCB modifications?

A: No. The devices use different package footprints: AP4460AEN uses 24-QFN (4x4) while TPS61200DRCR uses 10-VSON (3x3). PCB layout redesign is required for physical substitution.

Q: What are the key functional similarities between these devices?

A: Both are boost switching regulators with positive adjustable outputs, single output configuration, and integrated synchronous rectification. Both operate as step-up converters for low-voltage input applications.

Q: Are there voltage range differences I should consider?

A: Yes. The TPS61200DRCR accepts a wider input range (0.3V to 5.5V) versus the AP4460AEN (0.14V to 4V). The TPS61200DRCR also supports lower minimum output voltage (1.8V) compared to the AP4460AEN (2.5V). Verify your application requirements fall within the TPS61200DRCR specifications.

Q: What is the operating temperature difference?

A: The TPS61200DRCR operates from -40°C to 85°C, providing a 10°C lower minimum temperature compared to the AP4460AEN (-30°C to 85°C). Both meet standard industrial temperature ranges.

Q: Are there compliance or certification differences?

A: The TPS61200DRCR is RoHS3 compliant and REACH unaffected. Both devices share the same MSL rating of 2 (1 Year) and ECCN classification (EAR99).

Q: Why is the AP4460AEN obsolete?

A: The AP4460AEN is classified as obsolete by the manufacturer. The TPS61200DRCR from Texas Instruments is an active product offering equivalent functionality with improved specifications and ongoing supply availability.
