CMOS IC

ADAPTIVE 100/120Hz

CURRENT RIPPLE REMOVING

CIRCUIT CONTROLLER



DESCRIPTION

UTC ULD5133 is a controller, which drives external NMOSFET

to remove the 100/120Hz LED current ripple on AC/DC power by a

capacitor between VC and GND. The chip ensures minimum power

dissipation on NMOSFET while removing LED current ripple relying

on the adaptive technology.

UTC ULD5133 allows user to setup the maximum cathode

voltage of LED string by sensing the drain voltage of NMOSFET

which could help limit the power dissipation on chip.



FEATURES

* Controller for adaptive 100/120Hz current ripple remover

* Amplitude of LED current ripple programming

* Maximum cathode voltage of LED programming

* Maximum LED current programming
