Chip Advanced Technology CAT7117

The CAT7117 is a high efficiency step-down DC/DC converter using a constant frequency, current mode architecture. The device integrates a main switch and a synchronous rectifier for high efficiency without an external schottky diode. The CAT7117 can supply 800mA of load current from 2.5V to 5.5V input voltage.

GENERAL DESCRIPTION

Supply current during operation is only 300µA and drops to < 1µA in shutdown. The output voltage can be regulated as low as 0.6V. Switching frequency is internally set at 1.8MHz, allowing the use of small surface mount inductors and capacitor. It can also run 100% duty cycle for low dropout applications.
