M62500FP

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.
