초록

This paper presents a step-down converter IC for automotive applications. This device was designed for a 40V/1A high-power output for voltage reference of automotive IC. It provides 250kHz PWM(pulse width modulation) and PFM(pulse frequency modulation) according to load conditions. This device was simulated Spectre of IC Design Tool And fabricated Dong-bu Hitec 0.35um BD350BA process.
