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 SOP-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 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 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 accidental damage. - Automotive applications The internal fixed switching frequency of 120 k Hz, and the - Chargers for Ni Cd, Ni MH batteries SOP-8 package pin allow building an ultra pact DC/ DC - Simple step-down converters with converter with a minimum board space. adjustable current limit Features - Adjustable current generator - Up to 2A output current - Up to 90% Efficiency - Input Voltage Range: 8V 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. SD45216SA SD45216SATR SD45216SAG SD45216SAGTR SD45216JA SD45216JATR Package SOP-8-225-1.27 SOP-8-225-1.27 SOP-8-225-1.27 SOP-8-225-1.27 ESOP-8-225-1.27 ESOP-8-225-1.27 Marking 45216SA 45216SA 5216SAG 5216SAG 45216JA 45216JA HANGZHOU SILAN MICROELECTRONICS...
