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 malfunction 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 frequency
15 kHz to 150 kHz
•
Soft start function
