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. Integrated X-capacitor discharge resistors while Meeting IEC60950-1(ed.2) Safety requirements. APPLICATIONS AC/DC Switching Power Adaptor Battery Charger Open-Frame Switching Power Supply LED Power Supply FEATURES 700V CDMOS Process Auto Re-Start X2 Capacitor Discharge with load PIN CONFIGURATION SOT-23-5L SOT-23-5L Package Integrated X-capacitor discharge resistors (IEC60950-1(ed.2) Safety requirements.)
