POWER FACTOR CORRECTOR
F
Description
This device is power factor correction controller using a discontinues conduction mode of
boost converter. Especially, it is optimized for electronic ballasts which prevent abnormal
functions in load runaway and feedback loop fault conditions and low power and high
density power supplies which require minimum board size. The external component R/C
filter is not necessary because the R/C filter is included in current sense block. This is the
improved version with a pin out equivalent to world standard.
Features
Dynamic, Static & Feedback OVP
Extremely Low Start up Current (30uA Typ.)
Very Low Operating Current (4mA Typ.)
Internal Self Start Timer
Current Sense with Internal RC Filter
Trimmed 1.5% internal Reference
Under Voltage Lock Out with Hysteresis
Pin Compatible to World Standard

PIN Function
Pin Number
Pin Name
Pin Function Description
1 INV
Inverting input of the error amplifier. The output of the boost converter should be
resistively divided to 2.5V and Connected to this pin.
2 COMP
Output of the error amplifier. A feedback compensation network is placed
between this pin and the INV pin.
3 MULT
Input to the multiplier stage. The full wave rectified AC voltage is divided to less
than 4V and is connected to this pin.
4 CS
Input to the comparator of the control loop. The MOSFET current is sensed by a
resister and the resulting voltage is applied to this pin. An internal R/C filter is
Included to reject any high frequency noise.
5
IDET
Zero current detection input.
6
GND
Ground of the control section.
7 OUT
Gate drive output. A push pull output stage is able to drive the power MOSFET
with peak current of 500mA.
8
Vcc
Supply voltage of driver and control circuits.

Note : 1) Because the reference is not brought out externally, this specification can`t be tested on the package
Part. It is guaranteed by design.
2) This parameter, although guaranteed, is not tested in production.
