MEL7136B - Linear Adjustable Constant Current LED Driver

Download the MEL7136B datasheet PDF. This datasheet also covers the MEL7136A variant, as both devices belong to the same linear adjustable constant current led driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The MEL7136A 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.

The MEL7136B is only a controller , and must be connected to an external NMOS.

MEL7136A/MEL7136B Linear Adjustable Constant Current LED Driver MEL7136A/MEL7136B General Description The MEL7136A 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. The MEL7136B is only a controller , and must be connected to an external NMOS. MEL7136B is an external transistor, is suitable for applications requiring a high output current . The output current of ME7136B can be adjusted by external DC control voltage or PWM control. 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.
