Overview
The IS32LT3177 and IS32LT3178 are adjustable linear current devices with excellent temperature stability. A single resistor is all that is required to set the operating current from 10mA to 200mA. The devices can operate from an input voltage from 2.9V to 40V with a minimal voltage headroom of 1.0V (Typ.) at 150mA. Designed with a low dropout voltage; the device can drive LED strings close to the supply voltage without switch capacitors or inductors. The IS32LT3177/78 simplifies designs by providing a stable current without the additional requirement of inductors, FETs or diodes. The complete constant current driver requires only a current set resistor and a small PCB area making designs both efficient and cost effective. The EN Pin of the IS32LT3177 can be tied to V_BAT or PSM (Power Supply Modulation) signal for high side dimming. The EN Pin of the IS32LT3178 can function as the PWM signal input used for MCU PWM dimming. As a current sink it is ideal for LED lighting applications or current limiter for power supplies. The device is provided in a lead (Pb) free, SOT23-6 and SOP-8-EP packages.
