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

FUNCTION DESCRIPTION AND APPLICATION

M62213P/FP

(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 current­sense comp. with the controlled voltage.

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.

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.

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.

M62213P/FP

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 52KΩ or 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

Even if the timer function is not needed, latch function operates, that is, IC becomes inoperative when
the voltage of CT terminal is forced to be high voltage. Therefore, CT terminal can also be used for
OVP(over voltage protection).
When only OVP function is needed(timer latch function is not necessary), connect the resistor between
CT terminal and GND. In this case, the above mentioned charge current cannot make the voltage of CT
terminal rise up to "H" threshold, thus latch function does not operate. (Refer to Fig.5-1, 5-2)

(3) SOFT(DUTY SET-UP) TERMINAL

The voltage of SOFT terminal determines the maximum duty.
Maximum duty can be set by connecting the resistor as in Fig.6
because the constant current compensated for temperature flows
out of this terminal.
And by connecting the capacitor between the terminal and GND,
soft start function operates. That is, we can get the gradual
increase of maximum duty at start-up.
Maximum duty is represented as:

CSOFT

SOFT

VSOFT

Duty(max.) ≈ (40.5 * VSOFT) - 58 (%)
,where VSOFT=ISOFT * RSOFT (V), ISOFT ≈ 50µA(typ.)
If the voltage of SOFT terminal is higher than 3.53V(typ.)(upper limit

voltage of the oscillation waveform), maximum duty is internally decided
to be 90%.
Soft start time (TSOFT) is represented as:

TSOFT ≈ CSOFT * 31 * 103 (sec)
TSOFT means the time from start-up until the voltage of SOFT terminal

goes up to higher than 1.4V(typ.) (lower limit voltage of the oscillation
waveform).
Discharging circuit operative before start-up at Vcc is internally equipped
so that the soft start never fail to operate at the restart of voltage supply.

(4) CLM TERMINAL

This terminal is for pulse-by-pulse current limiting.
Current limiting circuit is almost the same as that of M51995.
The voltage detected by the current detecting resistor can be directly input as shown in Fig.7-1, if the
detected voltage is about the threshold voltage(200mV(typ.)), but if the voltage is larger than the
threshold, the voltage has to be input divided by resistors as shown in Fig.7-2.

1000pF to 22000pF is recommended for CNF. Be sure to use 100Ω or less for RNF and
RNF1// RNF2 (*)so that the detection sensitivity is not influenced by the current flown out from CLM
terminal.
Non-inductive resistor is recommended for current detecting resistor.

(5) CF TERMINAL

Oscillation frequency is set by capacitor connected to CF terminal.
The waveform of CF terminal is triangular one with the ratio of 9:1 for charge-discharge period.
Oscillation frequency is represented as:

fOSC = (Hz)

(19.4 * 103 * COSC) + (0.4 * 10-6)

(6) Attention for heat generation

Although the absolute maximum rating of ambient temperature is spelled out as 85˚C, it is
always annoying to specify the location this temperature refers to because the power
dissipation generated locally in switching regulator is fairly large and the temperature in the
vicinity of the IC varies from place to place.
One of the recommendable ways to solve this problem is to check the teperature on the
surface of the IC.
The difference in temperature between IC junction and the surface of IC package is 30˚C or
less when IC junction temperature is measured by utilizing the temperature characteristics of
p-n junction forward voltage, and the surface temperature by "thermo-viewer" on the condition
that the IC is mounted on the "phenol-base" PC board in normal atomosphere.
This concludes that maximum case temperature (surface temperature of IC package) rating is
100˚C with adequate margin considering the absolute maximum rating of junction temperature
is 150˚C.
