FAN53730 Datasheet | onsemi

DATA SHEET .onsemi. Buck Regulator 3 A, Constant On Time (COT) 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 m A - Internal Soft- Start Limits Input Current During Turn- On - 2.5 MHz Switching Frequency in Continuous Conduction Operation - 1.2 V and 1.8 V Logic patible - Fault Protection (Input Under Voltage, Short Circuit, Over Current, and Thermal) - Power Good Output (PG) - Forced Continuous Conduction Mode (FCCM) - Audio Reduction Mode Eliminates Audible Tones Due to Switching - - 40°C to +85°C Ambient Temperature Range - This is a Pb- Free Device Applications - LPDDR Memory - Mobile and Smart Devices - RF Modules WLCSP12 1.07 x 1.36 x 0.432, 0.35P CASE 567GK MARKING DIAGRAM XX ZZA YWW XX = Specific Device Code ZZ = Assembly Lot A = Site Code Y = Year WW = 2 Digit Work...
