Introduction
The FAN53555 is a step-down switching regulator that provides digitally programmable output from a 2.5V to 5.5V input voltage supply. The output voltage is programmable via an I2C interface capable of operating at frequencies up to 3.4MHz.
Using a dedicated architecture with synchronous rectification, the FAN53555 can deliver 5A of current at over 80% efficiency, and maintains efficiency above 80% even at load currents as low as 10mA. The 05 option supports pulse currents up to 6.5A. Operating at a nominal fixed frequency of 2.4MHz, the regulator allows the external output inductance to be reduced to 330nH and the output capacitance to 20uF. Additional output capacitance can be added without compromising stability to improve regulation during load transients. Inductors up to 1.2μH can be used together with the additional output capacitance.
At moderate and light loads, PFM enables the device to operate in a power-save mode with a typical quiescent current of 60uA. Even at this low quiescent current, the device demonstrates excellent transient response during large load swings. At higher loads, the system automatically switches to fixed-frequency operation at 2.4MHz. In shutdown mode, supply current drops below 1μA to reduce power consumption. PFM mode can be disabled when constant frequency operation is required. The FAN53555 is available in a 20-bump, 1.6×2mm WLCSP package.
