Application Note: SY8113B

High Efficiency, 500kHz, 3A, 18V Input

Synchronous Step Down Regulator

General Description

Features

The SY8113B is

a high efficiency 500 kHz

•

low R_DS(ON)for internal switches (top/bottom):

80m /40m

4.5-18V input voltage range

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 R_DS(ON)to minimize the conduction loss.

Ω

•

3A output current capability

500 kHz switching frequency

Instant PWM architecture to achieve fast transient

responses.

Cycle-by-cycle peak current limitation

Internal softstart limits the inrush current

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
