AN5757S
CRT horizontal deflection voltage control IC
■ Overview
The AN5757S is an IC for PWM-system CRT
horizontal deflection voltage control. It can be used
for horizontal frequency from 20 kHz to 140 kHz
and applicable from a popular type monitor to high
precision monitor. Its SO-16-pin package enables
the users to desigh the sets simple and efficient.
■ Features
• PWM output
• Built-in thermal protection circuit (cut off both
upper and lower push-pull output transistor)
• Soft start function
• Built-in error amp.
■ Applications
• CRT monitors
