GAMMA GM9601

GM9601
Universal LED Driver
for Super Bright LED Lighting
Description
Features
GM9601 is monolithic integrated circuit of a
general-purpose driver designed to control
brightness of LED lamps in wide limits.
The circuit is highly efficient for small sizes of
lighting-intended LED clusters.
‹
Internal built MOSFET
‹
EX pin current enabling to control LED
peak current, turn of and off
‹
Constant specified load current, which is
maintained with the wide range of input
voltage from 50V to 500V
‹
Over temperature protection (OPT)with
30°C hystereis
GM9601 is available in Power SO 8 package.
