SA57255-XX General Description


The SA57255-XX is a highly integrated DC/DC converter circuit. Efficient, compact power conversion is achieved with a pulse width modulation (PWM) controlled switching regulator circuit designed using CMOS processing. Low ripple and high efficiency of typically 83% are achieved through PWM control. The regulator has a high precision output with ±2.4% accuracy. Few external components are required.

The SA57255-XX has a built-in, soft-start circuit to reduce current inrush and voltage  overshoot during start up. The PWM control circuit is designed to drive an external low resistance NPN bipolar junction transistor (BJT). The DRIVE output provides typically 7 mA at 100 kHz typical switching frequency to drive the BJT.
