FAN53713
1.5 A Synchronous Buck
Regulator
Description
The FAN53713 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 FAN53713 is capable of delivering a peak efficiency
of 93%, while maintaining efficiency over 90% at load currents as low
as 1 mA.

The regulator operates with 0402 and 0603 input and output
capacitors, respectively, which reduces the total solution size to

(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.
