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 .

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.
