GENERAL PURPOSE HIGH SPEED PWM CONTROL IC
FUNCTION DESCRIPTION AND APPLICATION
(1) EA IN, EA OUT TERMINAL
Circuit for EAOUT terminal is connected to constant current
load(100µA typ.) shown in Fig.1. Output voltage of error
amp. is controlled by the output transistor to provide current-
sense comp. with the controlled voltage.
EA OUT

Fig.1 Circuit diagram of EAOUT terminal
Peripheral circuit of Error Amp
Detected voltage devided by R1 and R2 is input to EAIN terminal in such case as fly-back system where
VCC line voltage is proportional to output voltage, or in the case that the voltage detection is made on the
primary side. In this case operating region is set by R1 and R2, and AC gain by R1// R2, RF.

Fig.2 Method to detect the voltage on the primary side
In the case that feedforward system by photo-coupler is applied, following two methods are available.
One is the method by error amp. as in Fig.3-1, the other is by the direct connection to photo-coupler as in
Fig.3-2.
When photo-coupler is directly connected to EAOUT terminal, input terminal of error amp. is connected to
GND, photo-coupler is connected directly to EAOUT terminal.

GENERAL PURPOSE HIGH SPEED PWM CONTROL IC
In Fig. 3-1, AC gain is represented as:
| Av | = | RF/ RIN |
Proper gain setting is about 40dB.
RF should be 52Kor more due to the current source capability of error amp.
R1, R2 should meet the condition as below so that the voltage of EAIN terminal should not be over 5V.
R2 * Vcc/ (R1 + R2) 5V
Due to the input impedance of EAIN terminal, the current in R1, R2 should be less than several mA.
(2) CT(OVP) TERMINAL
Timer type latch circuit works as follows.
Constant charge current flows out from CT terminal to the external capacitor when CLM is operative.
When the voltage of CT terminal rises up to over 4.0V(typ.), the latch circuit operates to make
functions of this IC inoperative. Inoperative status is sustained until supply voltage becomes less than
stop voltage. The value for start-up register has to be set so that the current over 1.8mA(typ.) can flow
the resistor because the stop status has to be kept by the current in start-up resistor R1 shown in
application circuit.
When timer latch circuit is operative, supply current increases at high voltage as shown in Fig.4 to
avoid the damage caused by unnecessarily increased supply voltage.
Inoperative status goes back to operation by forcibly decreasing the voltage of CT terminal to less
than 0.7V.
