一,产品概述(General Description)

The JTML7136A 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 JTML7136B is only a controller , and must be connected to an
external NMOS. JTML7136B is an external transistor, is suitable for
applications requiring a high output current . The output current of
JTM7136B 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. Adding
an external NMOS or NPN transistor to this pin can extend current and
voltage range.
