Overview
SS6550 Low-Noise Synchronous PWM Step-Down DC/DC Converter n FEATURES l l l l n DESCRIPTION The SS6550 is a low-noise pulse-widthmodulated (PWM) DC/DC step-down converter, which can power logic circuits and transmitters in small wireless systems such as communicating PDAs, cellular phones and handy-terminals.
The device features an internal synchronous rectifier for high conversion efficiency.
Excellent noise characteristics and fixed-frequency operation provide easy post-filtering.
The SS6550 is ideally suited for Li-Ion battery applications.
It is also suitable for +3V or +5V fixed input applications.
The device operates in one of the following four modes.
Forced PWM mode operates at a...
