Output voltage is controlled by connecting photocoupler PC
1
between FB-terminal and GND terminal . When output voltage or
transmisslon waveform is unstable, connect C&R on both sides of PC
1
to reduce gain of control system.
5. Overcurrent detection circuit
This module detects drain current I
D
of MOS-FET, and minimize output pulse width by pulse-by-pulse at I
D
=2.5A TYP.
6. Overheat protection circuit
Overheat protection circuit starts to operate when internal temperature of IC is at 140C TYP. CA voltage V
CA
will be released from
clamped voltage 3.6V and the capacitor C
A
which is connected to CA terminal will be charged again by 10
μ
A of charge current.
When V
CA
increases to CA threshold voltageV
CA (OVP)
7.7V, internal constant voltage supply of IC becomes OFF-state and maintain
shut-down state. To maintain output shut-down condition, 0.3mA (Vcc=11V) TYP. is required. Output shut-down condition is
maintained even if lowering internal temperature of IC. To restart, Vcc needs to be lowered less than 9.3V by applying input voltage
again.
