FAN5358  
2MHz, 500mA, SC70 Synchronous Buck Regulator  
Features  
Description  
The FAN5358 is a step-down switching voltage regulator that  
delivers a fixed output from an input voltage supply of 2.7V to  
5.5V. Using a proprietary architecture with synchronous  
rectification, the device is capable of delivering 500mA and  
maintaining a very high efficiency of over 80% at load currents  
as low as 1mA. The regulator operates at a nominal frequency  
of 2MHz, which reduces the value of the external components  
to as low as 2.2μH for the output inductor and 4.7µF for the  
output capacitor.

1.0 to 1.8V Fixed Output Voltages  
Low Ripple, Light-Load PFM Mode  
Internal Soft-Start  
At moderate and light loads, pulse frequency modulation is  
used to operate the device in power-save mode with a typical  
quiescent current of 25µA. Even with such a low quiescent  
current, the part exhibits excellent transient response during  
large load swings. In shutdown mode, the supply current  
drops below 1µA, reducing power consumption.
