General Description
AIC1550COTR General Description
The AIC1550 is a low-noise pulse-width-modulated (PWM) DC-DC step-down converter. It powers logic circuits in PDAs and small wireless systems such as cellular phones, 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 AIC1550 is ideally suited for Li-ion battery applications. It is also suitable for +3V or +5V fixed input applications. The device can operate in either one of the following four modes.
