SY8022/SY8022L

High Efficiency 1 MHz, Dual 2.5A/2A

Synchronous Step Down Regulator

Preliminary Spec

General Description

The SY8022 and SY8022L are high-efficiency 1MHz

synchronous step-down DC-DC regulator ICs capable

of delivering up to 2.5A output currents. The SY8022

operates over a wide input voltage range from 3V to

5.5V and integrate 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 1MHz switching

frequency.

Applications

• Access Point Router

• Net PC

• LCD TV

• Set Top Box

Features

• low Rds(on) for internal switches (top/bottom):

SY8022: 150/100mohm, 2.5A

SY8022L: 180/120mohm, 2A

• 3-5.5V input voltage range

• 1MHz switching frequency minimizes the external

components

• Internal softstart limits the inrush current

• 100% dropout operation

• Compact and thermally enhanced package: SO8E
