FAN5350  
3MHz, 600mA Step-Down DC-DC Converter in  
Chip-Scale and MLP Packaging  
Features  
Description  
The FAN5350 is a step-down switching voltage regulator  
that delivers a fixed 1.82V from an input voltage supply  
of 2.7V to 5.5V. Using a proprietary architecture with  
synchronous rectification, the FAN5350 is capable of  
delivering 600mA at over 90% efficiency, while  
maintaining a very high efficiency of over 80% at load  
currents as low as 1mA. The regulator operates at a  
nominal fixed frequency of 3MHz at full load, which  
reduces the value of the external components to 1µH for  
the output inductor and 4.7µF for the output capacitor.

Synchronous Operation  
Power-Save Mode  
At moderate and light loads, pulse frequency modulation  
is used to operate the device in power-save mode with a  
typical quiescent current of 16µA. 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 3MHz. In shutdown mode, the  
supply current drops below 1µA, reducing power  
consumption.

Applications  
The FAN5350 is available in a 6-lead Molded Leadless  
Package (MLP) and a 5-bump Wafer Level Chip Scale  
Package (WLCSP).
