FAN8060 designed by Fairchild Semiconductor is a 1MHz, 1A integrated synchronous step-down regulator for DC-DC conversion that provides a peak efficiency of over 95 percent. FAN8060 step-down regulator offers a fast transient response time that swiftly responds to current fluctuations when there is a sudden change in load .The FAN8060 also allows a designer to simply adjust the external compensation to optimize the transient response for any condition. The user-selectable current limit provides protection against output overload and short circuit while its external synchronization pin reduces both EMI and crosstalk.
Main features of FAN8060 are : Current Mode Control , Over 96% Efficient , 2.5V to 5.5V Input Voltage Range , Output Voltage as Low as 1.2V , 1.2MHz Operating Frequency , Less than 1µA Shutdown Current , External Synchronization from 500kHz to 2MHz , 100% Duty Cycle , Synchronous Switching FET; no Schottky Diode Required , Overload / Short-Circuit Protection , Thermal Shutdown .
This Buck Regulator can be used in portable devices and other applications like : PDAs , GPS Dvices , MP3 Players , Digital Cameras , Peripheral Ports , DSP Core , USB Devices , Data Cards.
