M62502FP
PWM IC for the synchronized deflection system control
GENERAL DESCRIPTION
The M62502 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 and a
horizontal output correction of CRT monitors because of its
following circuits and functions;
• Under Voltage Lock Out circuit (UVLO)
• Soft-start function
