CM3708A - 3A LOW-NOISE PWM STEP-DOWN REGULATOR

Key Features

  • The CM3708A 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, communicating 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 CM3708A is ideally suited for Li-lon battery.

CM3708A 3A LOW-NOISE PWM STEP-DOWN REGULATOR GENERAL DESCRIPTION FEATURES The CM3708A 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, communicating 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 CM3708A 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 frequency regardless of the load.
