General Description
SA57254 General Description
The SA57254-XX is a fully 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 SA57254-XX has a built-in soft-start circuit which reduces inrush current and voltage overshoot during start-up. A low resistance CMOS power FET, which has low leakage current and low parasitic capacitance, is on-chip.
