FAN53745 Buck Regulator

FAN53745 Description

Buck Regulator, Synchronous, 3.33 MHz, 1 A FAN53745 .
The FAN53745 is a low quiescent current step. down DC/DC converter that delivers a regulated output voltage from an input supply of 2.

FAN53745 Features

* Proprietary Current Mode Architecture
* Wide Input Voltage Range: 2.3 V to 5.5 V
* 1 A Load Capability
* PFM / PWM Modes for High Efficiency
* I2C
* compatible Interface
* Programmable Output Voltage: 1.5 V to 3.3 V
* Programmable Current Limit: 440 mA to 2090 mA

FAN53745 Applications

* The converter normally operates in PWM Mode at a typical fixed
* frequency of 3.33 MHz. At moderate and light loads, the device will transition into PFM Mode to maintain high efficiency and excellent transient response. Additionally, a low power Shutdown Mode reduces power consumption when th
