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
compensation provides a stable and high efficient operation over a
SOP-8-225-1.27
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 m
assures high efficiency even at high output current level. The internal
limiting current of typical value of 3 A, output short and over APPLICATIONS
temperature protection, protect the device from accidental damage.
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
