onsemi FAN53741
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. 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. 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.| Part No. | FAN53741 |

DESCRIPTION
At moderate and light load, Pulse Frequency Modulation (PFM) is used to operate the device with a low quiescent current of 60 mA. Even with such a low quiescent current, the part exhibits excellent transient response during load swings. At higher loads, the system automatically switches to fixed−frequency control, operating at 2.5 MHz. In Shutdown Mode, the supply current drops below 0.5 mA, reducing power consumption. The FAN53741 is available in 6−bump, 0.4 mm pitch, Wafer−Level Chip−Scale Package (WLCSP).FEATURES
