SYNC-POWER SP689

SP689
Ultra High Voltage Start Up
DESCRIPTION
The SP689 is a low cost version ultra high voltage
start up IC. This IC is ideal to use in conjunction with
any PWM to further reduce the standby power. By
using SP689, it can eliminate the need for startup
resistors and bleeder resistors in switching mode
power supply design. It would provide the users a
superior AC/DC power application with higher
efficiency and lower standby power. With low
external component counts, SP689 is a low cost
solution for the applications.
SP689 is available in SOT-23-5L package.
