MITSUBISHI (Dig./Ana. INTERFACE)
M62500P/FP
SYNCHRONIZATION DEFLECTION SYSTEM CONTROL PWM IC
DESCRIPTION
The M62500 is a semiconductor integrated circuit designed and
developed as a deflection control of the CRT display monitor.
The built-in trigger mode oscillator allows stable PWM control to be
gained against a wide range of change of external signals.
The M62500 provides a low supply voltage output malfunction
preventive circuit (UVLO) and software start function optimum to
horizontal output correction of monitor, high voltage drive and high
voltage regulator.
