FAN53703

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

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.
