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
• The under voltage output malfunction protection circuit
start V_CC > 9 V
stop V_CC < 6 V
• Built-in over voltage protection (OVP) and under voltage protection (UVP) control
