SD45216_Datasheet
HIGH EFFICIENCY STEP-DOWN DC/DC CONVERTER WITH ADJUSTABLE CURRENT LIMIT FOR AUTOMOTIVE APPLICATIONS
DESCRIPTION
The SD45216 is a high efficiency step down DC-DC converter
with adjustable current limit in compact SOP-8 package,
including an error amplifier, ramp generator, current comparator,
slope compensation, current sense and logic driver. It also
integrates a current error amplifier to have a constant voltage
and constant current control.
Peak current mode PWM control with external adjustable
compensation provides a stable and high efficient operation over
a wide range of load currents. By means of an on board current
sense resistor and the availability of the current sense pins, a
current limit programming is very simple and accurate.
