DATA SHEET www.onsemi.com Buck Regulator 3 A, Constant On Time (COT) FAN53730 Description The FAN53730 is a constant on time (COT) buck converter that supports a minimum of 3 A load current. The device’s COT topology provides the fastest transient recovery and optimal efficiency vs load due to its variable frequency operation. Two device options are available (see Ordering Information): ♦ I2C Controlled ♦ Logic Controlled (pin selectable VOUT) Both options have automatic DCM/CCM mode operation with Forced CCM control. Features • Input Voltage Range: 2.3 V to 5.5 V • Output Voltage: ♦ Programmable from 0.3 V to 2 V ♦ Pin Selectable Defaults • Low Quiescent Current: 12 mA • Internal Soft−Start Limits Input Current During Turn−On • 2.
