APR34509LMPTR-G1

Power Supply Controllers, Monitors Overview

The APR34509LMPTR-G1 is a secondary side synchronous rectification controller manufactured by Diodes Incorporated. It operates within an input voltage range of 3.3 V to 13 V and supports output voltages from 5 V to 12 V. The device utilizes a flyback topology and is housed in an 8-SOIC package with an exposed pad (SO-8EP). It features a low operating supply current of 100 uA and supports a maximum output current of 20 A. The component is rated for operation up to +150°C and includes humidity sensitivity classification.

Power Supply Controllers, Monitors Feature Summary

• Integrated synchronous rectification control for flyback AC/DC converters
• Low quiescent current consumption for improved efficiency
• Exposed pad package design for enhanced thermal dissipation

Power Supply Controllers, Monitors Applications

• Secondary side control in offline flyback power supplies
• AC/DC converter systems requiring synchronous rectification
• Power management ICs for consumer electronics adapters

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'L' against official Diodes Incorporated documentation, as standard listings often reference the 'M' variant. Confirm package dimensions and pinout compatibility with your PCB layout. Ensure compliance with RoHS directives and check moisture sensitivity levels prior to surface mount assembly processes.

Power Supply Controllers, Monitors Selection Notes

Select this component for applications requiring secondary side synchronization in flyback topologies. Compare the SO-8EP package against available alternatives like the APR34509MPTR-G1 if the exposed pad is not required. Validate that the 13 V maximum input voltage aligns with your system's operational range and that the 20 A output capability meets load requirements.

Power Supply Controllers, Monitors Part Context

This part belongs to the APR345 series of AC/DC converters from Diodes Incorporated. It functions as a secondary side controller designed to replace traditional diode rectifiers, thereby reducing conduction losses. The series is categorized under PMIC solutions for efficient power conversion in isolated switching applications.

Power Supply Controllers, Monitors Replacement Considerations

The APR34509MPTR-G1 is a documented equivalent variant within the same product family. Verify if the 'M' suffix denotes a minor manufacturing or packaging difference compared to the 'L' suffix before substitution.
