  • The FAN53526 is a step-down switching voltage regulator that delivers a digitally programmable output from an input voltage supply of 2.5V to 5.5V. The output voltage is programmed through an I2C interface capable of operating up to 3.4MHz.Using a proprietary architecture with synchronous rectification, the FAN53526is capable of delivering 3.0A continuous at over 80% efficiency, maintaining that efficiency at load currents as low as 10mA. The regulator operates at a nominal fixed frequency of 2.4MHz, which reduces the value of the external components. Additional output capacitance can be added to improve regulation during load transients without affecting stability. At moderate and light loads, Pulse Frequency Modulation (PFM) is used to operate in Power-Save Mode with a typical quiescent current of 50μAat room temperature. Even with such a low quiescent current, the part exhibits excellent transient response during large load swings. At higher loads, the system automatically switches to fixed-frequency control, operating at 2.4MHz. In Shutdown Mode, the supply current drops below 1μA, reducing power consumption. PFM Mode can be disabled if fixed frequency is desired. The FAN53526is available in a 15-bump, 1.310mmx 2.015mm, 0.4mm ball pitch WLCSP.
