MP4653 - LLC TV LED Driver

Description

The MP4653 is a CC/CV mode LLC TV LED driver for LED backlighting, especially for large size TV LED backlighting.

Powered by 9V to 30V input supplies, the MP4653 outputs two 180 degree phase shifted driving signals for the external power stages.

Features

  • sufficient and smart protection to increase system reliability. It protects the fault condition at both the DC bus stage and the LED driver stage. The protection for the DC bus stage includes the over voltage protection and over current protection (short protection). MP4653 Real LIPS CC/CV Mode LLC TV LED Driver The protection for the LED driver stage includes the open LED protection, short LED protection, over LED current protection and any point of LED string short to ground protection.

The Future of Analog IC Technology DESCRIPTION The MP4653 is a CC/CV mode LLC TV LED driver for LED backlighting, especially for large size TV LED backlighting. Powered by 9V to 30V input supplies, the MP4653 outputs two 180 degree phase shifted driving signals for the external power stages. Its enhanced 9V gate driver provides adequate driving capability and can directly drive the external MOSFETs through an external gate driving transformer. The MP4653 integrates a constant current control loop for the LED current regulation and also a constant voltage control loop for the DC bus voltage, which is used to generate system power supplies like 12V/5V with other DC/DC converters.
