MP4653GY-Z

Overview

The MP4653GY-Z is a single-channel LED lighting driver IC from Monolithic Power Systems, designed for LLC TV LED driver applications. It operates within an input voltage range of 9 V to 30 V and features a fixed switching frequency of 38.6 kHz. The device supports PWM dimming and provides constant current/constant voltage regulation modes. Packaged in a SOIC-20 surface-mount format, it functions reliably across a temperature range of -40°C to +125°C with a maximum power dissipation of 1.7 W.

Feature Summary

Supports Real LIPS CC/CV Mode operation for precise LED control
Integrates PWM dimming capability for brightness adjustment
Includes internal protection mechanisms such as over-temperature and under-voltage lockout

Applications

LED backlighting systems for televisions
LLC resonant converter designs for display drivers
General LED lighting driver circuits requiring constant current regulation

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and halogen-free status according to manufacturer documentation. Confirm the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the design accommodates the specified 38.6 kHz switching frequency and thermal dissipation limits for the intended operating environment.

Selection Notes

Select this component for applications requiring a dedicated LLC controller with integrated dimming features. It is suitable for designs needing a wide input voltage range up to 30 V. Consider the SOIC-20 package size and thermal performance when evaluating alternatives. Verify compatibility with external MOSFETs and passive components for the resonant tank circuit.
