Application Note: SY8113B
High Efficiency, 500kHz, 3A, 18V Input
Synchronous Step Down Regulator
General Description
The SY8113B is a high efficiency 500 kHz
synchronous step-down DC-DC converter capable of
delivering 3A current. The SY8113B operates over a
wide input voltage range from 4.5V to 18V and
integrates main switch and synchronous switch with
very low RDS(ON) to minimize the conduction loss.
Low output voltage ripple and small external inductor
and capacitor sizes are achieved with 500 kHz
switching frequency. It adopts the instant PWM
architecture to achieve fast transient responses for high
step down applications
