SD45215_Datasheet HIGH EFFICIENCY STEP-DOWN DC/DC CONVERTER WITH ADJUSTABLE CURRENT LIMIT FOR AUTOMOTIVE APPLICATIONS DESCRIPTION The SD45215 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 SOP-8-225-1.27 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.
