Overview
The AP62300TWU-7 is a synchronous step-down DC-DC converter manufactured by Diodes Incorporated. It operates with an input voltage range of 4.2 V to 18 V and delivers up to 3 A of output current. The device features adjustable output voltages from 800 mV to 7 V, utilizing a fixed switching frequency of 750 kHz. Packaged in a TSOT-26-6 surface-mount format, it supports operation within a temperature range of -40°C to +85°C.
Feature Summary
- Synchronous buck topology for high efficiency
- Integrated loop compensation reduces external component count
- Built-in protection against overcurrent, overvoltage, and thermal stress
Applications
- Portable electronic devices requiring efficient power regulation
- Industrial control systems with moderate voltage inputs
- Consumer electronics utilizing single-rail power architectures
Procurement Notes
Verify the specific suffix designation against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure that the ordering information matches the exact part number variant required for your design, as minor suffix changes may indicate different packaging or testing criteria defined by Diodes Incorporated.
Selection Notes
Select this component when designing circuits requiring a wide input voltage range up to 18 V and an output current capacity of 3 A. The TSOT-26-6 package is suitable for space-constrained applications. Confirm that the target output voltage falls within the adjustable range of 800 mV to 7 V and that the operating environment remains within the specified industrial temperature limits.
Part Context
This device belongs to the AP62300 series of high-voltage buck converters from Diodes Incorporated. It is designed for applications needing robust performance in compact form factors. The series utilizes constant on-time control to manage wide input-to-output voltage ratios effectively while maintaining stability with low-ESR ceramic capacitors.
Replacement Considerations
The RT6253AHGJ6F is documented as a similar alternative. Verify compatibility regarding input voltage limits, as the RT6253AHGJ6F specifies a maximum input of 17 V compared to the 18 V limit of the AP62300TWU-7.
