300 mA / 600 mA / 1 A  
Synchronous Buck Regulator  
Description  
www.onsemi.com  
The FAN5370X is a Super Low Iq, 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 FAN5370X is capable of delivering a peak efficiency  
of 93%, while maintaining efficiency over 90% at load currents as low  
as 1 mA.  
WLCSP6  
CASE 567UH  
The regulator operates with 0402 and 0603 input and output  
capacitors, respectively, which reduces the total solution size to  
2
5.5 mm . At moderate and light load, Pulse Frequency Modulation  
(PFM) is used to operate the device with a low quiescent current. Even  
with such a low quiescent current, the part exhibits excellent transient  
response during load swings. In Shutdown Mode, the supply current  
drops to 100 nA, reducing power consumption. The Mode pin allows  
the part to be in a Super Low IQ (SLIQ) mode with a typical quiescent  
current of 2 mA.
