The MP4653GY-P is a Real LIPS CC/CV LLC LED driver controller from Monolithic Power Systems, designed for large LCD TV backlight applications. It operates on a 9V to 30V input supply and features an enhanced 9V gate driver capable of directly driving external MOSFETs via a transformer. The device integrates constant current and constant voltage control loops to regulate LED current and DC bus voltage. It supports both analog and PWM dimming, outputting drive signals for direct dimming MOSFET control to ensure high contrast and audible noise elimination during PWM operation.
Verify the specific suffix 'P' against official MPS documentation to confirm package and tape/reel specifications. Ensure compatibility with SOIC-20 footprint requirements. Cross-reference humidity sensitivity classifications and operating temperature ranges (-40°C to +125°C) with your design constraints before finalizing procurement.
Select this component for applications requiring precise LED current regulation combined with DC bus voltage control in large display systems. The integrated dual-loop control simplifies design complexity by managing both LED brightness and system power rails simultaneously. Consider the enhanced gate driver capability when selecting external MOSFETs to ensure efficient direct driving without additional buffer stages.
The MP4653 belongs to the MP4653 series of Real LIPS LLC LED driver controllers. It is specifically engineered for television backlighting where noise reduction and high efficiency are critical. The part complements other MPS power management solutions by providing specialized control for LLC resonant converters in display applications.
MP4653GY-Z is a confirmed substitute within the same series offering identical functional characteristics.
