IS32LT3958A - HIGH VOLTAGE LED LIGHTING CONTROLLER
The IS32LT3958A is a current mode PWM controller designed to drive a low side external NMOS FET for wide input/output voltage range and high LED current applications.
An external resistor senses the high side output current of the LED string.
A high side sense resistor is the most flexible current s
IS32LT3958A Features
* two independent analog dimming pins, ICTRL and ADJR. Input DC voltage in the range of 0.06V~2V on the ICTRL pin and/or ADJR pin is required for analog dimming. PWM dimming is achieved by directly modulating the PWM/EN pin with desired PWM duty cycle or by enabling the internal PWM generator circuit.
