MAX887, MAX887H 100% Duty Cycle, Low-Noise, Step-Down, PWM DC-DC Converter

The MAX887 high-efficiency, Step-down DC-DC Converter provides an adjustable output from 1.25V to 10.5V. It accepts inputs from 3.5V to 11V and delivers 600mA. Operation to 100% duty cycle minimizes dropout voltage (300mV typ at 500mA). Synchronous rectification reduces output Rectifier losses, resulting in efficiency as high as 95%.
Fixed-frequency pulse-width modulation (PWM) reduces noise in sensitive Communications applications. Using a high-frequency internal Oscillator allows tiny surface-mount components to reduce PC board area, and eliminates audio-frequency interference. A SYNC input allows synchronization to an external Clock to avoid interference with sensitive RF and data-acquisition circuits.
The MAX887 features current-mode operation for superior load/line-transient response. Cycle-by-cycle current limiting protects the internal MOSFET and Rectifier A low-current (2.5A typ) shutdown mode conserves battery life.
