SP9718 - 1.5A LOW-NOISE PWM STEP-DOWN REGULATOR

General Description

The SP9718 is low-noise pulse-width-modulated, DC-DC step-down converter.

It powers logic and transmitters in small wireless systems such as cellular phones, communicating PDAs, and handy-terminals.

Key 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 SP9718 is ideally suited for Li-Ion battery.

SP9718 1.5A LOW-NOISE PWM STEP-DOWN REGULATOR DESCRIPTION The SP9718 is low-noise pulse-width-modulated, 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 SP9718 is ideally suited for Li-Ion 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. Shutdown mode places the device in standby, reducing quiescent supply current to under 0.1μA.
