3.0A Step Down Switching Voltage Regulator

The FAN53527 is a step−down switching voltage regulator with an input voltage supply range of 2.5 V to 5.5 V. Device settings can be programmed through an I2C interface, or the IC can be operated in stand-alone mode with pin controls for enable, output voltage, and Auto PFM or Forced PWM operation.Using a proprietary architecture with synchronous rectification, the FAN53527 is capable of delivering 3.0A continuous at over 80% efficiency, and maintain that efficiency with load currents as low as 10mA. At moderate and light loads, Pulse Frequency Modulations(PFM) is used to operate in Power-Save Mode where excellent transient response is maintained. In Shutdown Mode, the supply current drops below 1 μA, further reducing power consumption. At higher loads, the device automatically switches to fixed-frequency PWM control, operating at 2.4MHz.The FAN53527 is available in a 15-bump, 1.310 mm x 2.015 mm, 0.4 mm ball pitch, Wafer-Level Chip-Scale Package (WLCSP).
