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
