Preliminary Datasheet for Engineering Sample
SGM3752 38V High Efficiency, Boost WLED Driver
with PWM Control
GENERAL DESCRIPTION
With a 40V rated integrated switch FET, the SGM3752 is a boost converter that drives LEDs in series.
The boost converter has a 40V, 1.
5A internal
MOSFET; thus it can drive single or parallel LED strings for small to large size panel backlighting.
The default white LED current is set with the external sensor resistor, RSET, and the feedback
voltage is regulated to 200mV, as shown in the typical application.
During the operation, the LED current can be controlled by using a pulse width modulation (PWM) signal applied to the CTRL pin, through which the duty cycle de...
