ICE3BR4765JZ 3BR4765JZ DIP7
The CoolSET®
-F3R, ICE3BRxx65J(Z)(G) is the latest development of the CoolSET®
-F3. It is a PWM
controller with power MOSFET and startup cell in a DIP or DSO package. The switching frequency is running
at 65 KHz and it targets for DVD player, set-top box, portable game console, auxiliary power supply, etc.
The ICE3BRxx65J(Z)(G) adopts the BiCMOS technology and provides a wider Vcc operating range up to
25V. It inherits the proven good features of CoolSET®
-F3 such as the active burst mode achieving the lowest
standby power, the propagation delay compensation making the most precise current limit control in wide
input voltage range, etc. In addition, it also adds on some useful features such as built-in soft start time, builtin basic with extendable blanking time for over load protection and built-in switching frequency modulation (
frequency jittering ), external auto-restart enable, etc

توضیحات
Functions : This is a kind of semiconductor, Off-Line SMPS Current Mode Controller with
integrated 650V CoolMOS® and Startup cell.
Startup time is counted from applying input voltage to IC turn on. ICE3BRXX65J(Z)(G) has a startup cell
which is connected to input bulk capacitor. When there is input voltage, the startup cell will act as a constant
current source to charge up the Vcc capacitor and supply energy to the IC. When the Vcc capacitor reaches
the Vcc_on threshold 18V, the IC turns on. Then the startup cell is turned off and the Vcc is supplied by the
auxiliary winding. Start up time is independent from the AC line input voltage and it can be calculated by the
