SYNCHRONIZATION DEFLECTION SYSTEM CONTROL PWM IC

M62500P/FP

MITSUBISHI (Dig./Ana. INTERFACE)

(

/ 11 )

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.

FEATURES

PWM output in synchronization with external signals

Wide range of PWM control frequency

15kHz to 150kHz

The PWM output phase is adjustable against external signals

Soft start

Built-in low voltage output malfunction prevention circuit
