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
