IT77117
Dual Channel 5V/800mA High Efficiency Step-Down DC/DC Converter
Description
The IT77117DF 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 supply current during operation is 320µA only and will drop below 1µA after shutdown.
The IT77117DF can supply 800mA of load current from 2.
5V to 6.
0V input voltage.
The output voltage can be regulated as low as 0.
6V.
The switching frequency is internally set at 1.
2MHz, allowing the use of small surface mount inductors and capacitor.
