Features

• Good load regulation over a wide load for external

components.

• Internal soft-start for quiet start-up.

• Start-up supply current less than 1.6mA.

• Switch-oft supply current less than 10mA.

• Burst operation under short-circuit conditions

• Thermal shutdown through over-temperature.

Description

The KA7515 provides the necessary features to implement

switching mode power supply with a minimal external parts

count. Internally implemented circuits include 3V refer-

ence voltage block, supply voltage monitoring block to

control output through supply voltage and overload amplifier

block to control output by external road variation. The

KA7515 controls the power MOSFET and performs all

necessary regulation and monitoring function in free running

flyback converters.
