Buck Regulator, 3.0 A FAN53527 Descriptions 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 3.0 A continuous at over 80% efficiency, and maintain that efficiency with load currents as low as 10 mA. At moderate and light loads, Pulse Frequency Modulation (PFM) is used to operate in Power−Save Mode where excellent transient response is maintained. In Shutdown Mode, the supply current drops below 1 mA, further reducing power consumption.
