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

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