1.5A LOW-NOISE PWM STEP-DOWN REGULATOR
GENERAL DESCRIPTION
Features
The CM3718C is a low-noise, pulse-width-modulated (PWM), DC-DC step-down converter. It powers logic and transmitters in small wireless systems such as cellular phones, municating PDAs, and handy-terminals. The device Features an internal synchronous rectifier for high efficiency; it requires no external Schottky diode. Excellent noise characteristics and fixed-frequency operation provide easy post-filtering. The CM3718C is ideally suited for Li-lon battery applications. It is also useful for +3V or +5V fixed input applications.
The device operates in one of four modes. Forced PWM mode operates at a fixed...
