General Description

SY7088 is a high efficiency synchronous boost

regulator that converts up to 5.5V output voltage. It

adopts NMOS for the main switch and PMOS for the

synchronous switch. It can disconnect the output from

input during the shutdown mode.

Features

· 2.3-5.0V input voltage range

· Adjustable output voltage from 2.5V to 5.5V

· Pseudo-constant frequency: 1MHz

· 3A peak current limit

· Input under voltage lockout

· Load disconnect during shutdown

· Output over voltage protection

· Low RDS(ON) (main switch/synchronous switch)

at 5.0V output: 70/100mohm

· Compact package: DFN2x3-8

Applications

· All Single Cell Li or Dual Cell Battery Operated

Products as MP-3 Player, PDAs, and Other

Portable Equipment.
