Description
General part information
FAN53741 Series
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 provides a fixed output voltage ranging from 0.6V to 3.3V, and can be programmed in 25mV steps via I2C. 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 µA. 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 µA, reducing power consumption. The FAN53741 is available in 6-bump, 0.4 mm pitch, Wafer-Level Chip-Scale Package (WLCSP).
