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.
