Silan SD45216SA
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. 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.

APPLICATIONS
DESCRIPTION
Peak current mode PWM control with external adjustable compensation provides a stable and high efficient operation over a wide range of load currents. The internal robust P-channel DMOS transistor with a typical of 100 mΩ assures high efficiency even at high output current level. The internal limiting current of typical value of 3 A, output short and over temperature protection, protect the device from APPLICATIONS
