FAN5361  
6MHz, 600mA TinyBuck™ Synchronous Buck Regulator  
Features  
Description  
„ 6MHz Fixed-Frequency Operation  
„ 35µA Typical Quiescent Current  
„ Best-in-Class Load Transient  
The FAN5361 is a 600mA, step-down, switching voltage  
regulator that delivers a fixed output from an input voltage  
supply of 2.3V to 5.5V. Using a proprietary architecture with  
synchronous rectification, the FAN5361 is capable of  
delivering a peak efficiency of 92%, while maintaining  
efficiency over 80% at load currents as low as 1mA.  
„ 600mA Output Current Capability  
„ 2.3V to 5.5V Input Voltage Range  
„ 1.0 to 1.82V Fixed Output Voltage  
„ Low Ripple Light-Load PFM Mode  
„ Forced PWM and External Clock Synchronization  
„ Internal Soft-Start  
The regulator operates at a nominal fixed frequency of 6MHz,  
which reduces the value of the external components to 470nH  
for the output inductor and 4.7µF for the output capacitor. The  
PWM modulator can be synchronized to an external frequency  
source.  
„ Input Under-Voltage Lockout (UVLO)  
„ Thermal Shutdown and Overload Protection  
„ 6-bump WLCSP, 0.4mm Pitch  
„ 6-pin 2 x 2mm UMLP  
At moderate and light loads, pulse frequency modulation is  
used to operate the device in power-save mode with a typical  
quiescent current of 35µA. Even with such a low quiescent  
current, the part exhibits excellent transient response during  
large load swings. At higher loads, the system automatically  
switches to fixed-frequency control, operating at 6MHz. In  
shutdown mode, the supply current drops below 1µA,  
reducing power consumption. For applications that require  
minimum ripple or fixed frequency, PFM mode can be  
disabled using the MODE pin.  
Applications  
„ Cell Phones  
„ Portable Media Players  
„ WLAN, 3G, and 4G Data Cards  
The FAN5361 is available in 6-bump, 0.4mm pitch, Wafer-  
Level Chip-Scale Package (WLCSP) and a 6-lead 2 x 2mm  
ultra-thin MLP package.
