The SGM3727 is a step-up DC/DC converter designed
for driving the white LEDs with an externally
programmable constant current. This device features
integrated, 38V power MOSFET that is capable of driving
up to 10 white LEDs in series, providing inherent current
matching for uniform brightness. WLED brightness
adjustment is easily achieved via a single wire interface,
totally 32 brightness levels of LED Dimming.
The SGM3727 features a variety of protection circuits,
including integrated over-voltage protection (OVP),
soft-start, cycle-by-cycle current limiting, and thermal
shutdown protection circuitry. SGM3727YDE8G/TR资料下载
