SP689AS25RGB
SP689A 是一款高壓啟動IC.
HV電壓能達到700V.
SP689A 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 SP689A, 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, SP689A is a low cost
solution for the applications.
SP689A is available in SOT-23-5L package
可有以下應(yīng)用：
AC/DC Switching Power Adaptor
Battery Charger
Open-Frame Switching Power Supply
LED Power Supply
