PWM IC for the synchronized deflection system control

GENERAL DESCRIPTION

The M62501P/FP is a controller for a deflection system of
CRT display monitors. It performs a stable PWM control over
a wide fluctuation of external signals, thanks to the built-in
trigger mode oscillator. The IC is suitable for an application to
a high voltage drive of monitors because of its following
circuits and functions;

• low voltage mulfunction protection circuit,

• over or under voltage protection circuit for a control line,

• soft-start function.
It is also applicable to a horizontal output correction.

FEATURES

• PWM output synchronized with external signals

• Wide pulse width modulation control frquency
15kHz to 150kHz

• Soft start function

• The under voltage output malfunction protection circuit
start Vcc > 9V stop Vcc < 6V

• Built-in over voltage protection (OVP) and under voltage
protection (UVP) control

C1,C2 Stabilization capacitors of Vcc and VREF.
VR1 It is decided considering a load capacity of VREF.

(A load capacity is approximately 5mA.)
Recommended value is around 10kΩ.

C3,D1 They are for the soft start function. A time constant is decided considering VR1.
Cagc This capacitor is for stabilization of AGC. A larger capacitor improves a stability of the

system, however a system response is degraded.
Recommended value is around 1µF.

Cosc This capacitor is for a saw wave generation. Recommended value is around 1000pF.
R1,R2,R3,R4 They are for a gain setting of the error Amp. R2 should be several kΩ to dozens of kΩ

C4,C5 to set a voltage gain 20dB to 40 dB at f = 1kHz, so that the feed back loop is stable.
When the voltage gain is too low, it causes jitter.
Recommended values of C4, C5 and R1 are ;
C4 = dozens of pF to several hundreds pF
C5 = several thousands pF to tens of thousands pF
R1 = dozens of kΩ to several hundreds kΩ.

*Annotation:Connect 7pin and 8pin terminal to GND when don't use under voltage protection (UVP).
