Features and benefits

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 dimmin.

Application

An external resistor senses the high side output current of the LED string. A high side sense resistor is the most flex.

Description

The IS32LT3958 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 s.
