HM7136 - Adjustable Constant Current LED Driver

Datasheet Summary

Description

The +0 is a constant current regulator for driving LEDs with low quiescent current and low dropout voltage.

The current is adjustable from 10mA to1A with an external resistor.

Only one external resistor is required to achieve a constant current LED driver.

Features

  • z Sink current:10mA to1A adjustable with an external resistor z Current and voltage range extendable by adding an external NMOS or NPN transistor z Power supply voltage: 2.7-18V z Low drop out voltage: 50mV@1A z Low quiescent current: 80uA z Thermal Shutdown protection：165℃ z Soft start z Low voltage protection: 2.5V z Package:SOT89-5,ESOP8. Selection Guide Typical.

+0 Adjustable Constant Current LED Driver +0 General Description The +0 is a constant current regulator for driving LEDs with low quiescent current and low dropout voltage. The current is adjustable from 10mA to1A with an external resistor. Only one external resistor is required to achieve a constant current LED driver. Soft start ,thermal protection and low voltage protection are also provided. The driver pin EXT is provided for current and voltage extension. Adding an external NMOS or NPN transistor to this pin can extend current and voltage range. Features z Sink current:10mA to1A adjustable with an external resistor z Current and voltage range extendable by adding an external NMOS or NPN transistor z Power supply voltage: 2.
