Overview
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.
The internal robust PMOS transistor with a typical of 150 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 accidental damage.
APPLICATIONS The internal fixed switching frequency of 120 kHz, and the SOP-8 * Automotive applications package pin allow building an ultra compact DC/ DC converter with a * Chargers for NiCd, NiMH batteries minimum board space.
* Simple step-down converters with adjustable current limit * Adjustable current generator FEATURES * Up to 1.
5A output current * Up to 90% Efficiency * Input Voltage Range: 8V to 30V * 120 kHz Internal Jitter Frequency for lower EMI * Patent -Pending Short Circuit Protection * Patent -Pending Output Voltage Compensation * Adjustable current limit * Over Temperature Protection * Small SOP-8 Package ORDERING INFORMATION Part No.
