SJ7500 Overview
The SJ7500 is a monolithic integrated circuit which includes all the necessary building blocks for the design of pulse width modulate(PWM) switching power supplies, including push-pull, bridge and series configuration. The precision of voltage reference is improved up to ±1% through trimming and this provides a better output voltage regulation. The device can operate at switching frequencies between 1KHz and 300KHz...
