FAN53713 1.5 A Synchronous Buck Regulator Description The FAN53713 is a Super Low Iq, step−down switching voltage regulator, that delivers a fixed output from an input voltage supply of 2.3 V to 5.5 V. Using a proprietary architecture with synchronous rectification, the FAN53713 is capable of delivering a peak efficiency of 93%, while maintaining efficiency over 90% at load currents as low as 1 mA. The regulator operates with 0402 and 0603 input and output capacitors, respectively, which reduces the total solution size to 5.5 mm2. At moderate and light load, Pulse Frequency Modulation (PFM) is used to operate the device with a low quiescent current. Even with such a low quiescent current, the part exhibits excellent transient response during load swings.
