Abstract

This paper presents a step-down converter IC for automotive applications. This device was designed for a 40 V/1 A 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-tools and fabricated Dong-bu Hitec 0.35um BD350BA process.
