DATA SHEET www.onsemi.com Synchronous Buck Regulator, 2.5 MHz FAN53741 WLCSP6 1.38x0.94x0.625 CASE 567UH Description The FAN53741 is a 2.5 MHz 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 FAN53741 is capable of delivering a peak efficiency of 97% and can support a max load of 1300 mA. The regulator operates at a nominal fixed frequency of 2.5 MHz, which reduces the value of the external components achieving a total solution size of 5.24 mm2. At moderate and light load, Pulse Frequency Modulation (PFM) is used to operate the device with a low quiescent current of 60 mA.
