Overview
com INTELLIGENT VOLTAGE MODE PWM IC GENERAL DESCRIPTION The KA3511/D is a fixed-frequency improvedperformance pulse-width modulation control circuit with complete housekeeping circuitry for use in the secondary side of SMPS (Switched mode power supply).
It contains various functions, which are precision voltage reference, over voltage protection, under voltage protection, remote on/off control, power good signal generator and etc.
OVP (Over voltage protection) section It has OVP functions for +3.
3V,+5V,+12V and PT outputs.
The circuit is made up of a comparator with four detecting inputs and without hysteresis voltage.
Especially, PT (Pin16) is prepared for an extra OVP inpu...
