MB3817 Overview
The MB3817 is a pulse width modulator (PWM) type switching regulator controller IC designed for low-voltage and high-speed operation. This can be used in applications as down-conversion or down/up-conversion (Zeta method). With fewer external ponents and faster operating speed, the MB3817 enables reduction in power supply unit size, making it ideal for use with internal power supplies in pact, high-performance...
