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 pact ESOP-8 package, including an error amplifier, ramp generator, current parator, slope pensation, 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 pensation provides a stable and high efficient operation over ESOP-8-225-1.27 (With heatsink at the bottom) 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. The internal robust PMOS transistor with a typical of 100 mΩ assures high efficiency even at high output current level. The APPLICATIONS internal limiting current of typical value of 3.5 A, output short and over temperature protection, protect the device from accidental damage. The internal fixed switching frequency of 120 k Hz, and the ESOP-8 package pin allow building an ultra pact DC/ DC converter with a minimum board space. - Automotive applications - Chargers for Ni Cd, Ni MH batteries - Simple step-down converters with adjustable current limit - Adjustable current generator Features - Up to 2.1A output current - Up to 90% Efficiency - Operating voltage can be up to 40V - 120 k Hz Internal Jitter Frequency for lower EMI - Patent -Pending Short Circuit Protection - Patent -Pending Output Voltage pensation - Adjustable current limit - Over Temperature Protection - Small SOP-8 Package ORDERING INFORMATION Part No. SD45216JA SD45216JATR SD45216RJA SD45216RJATR Package ESOP-8-225-1.27 ESOP-8-225-1.27 ESOP-8-225-1.27 ESOP-8-225-1.27 Marking 45216JA 45216JA 5216RJA 5216RJA Material Pb free Pb free Pb free Pb free Packing Tube Tape&Reel Tube...
