80W 24V Adapter with ICE2B765P on Board
Introduction
Application
This document is an engineering report that describes a universal input power supply designed in a
typical off line flyback converter topology that utilizes the ICE2B765P CoolSET. The application
1
operates in discontinuous current mode using the frequency reduction during standby condition
. The
board has one output voltage with secondary regulation.
This board demonstrates the basic performance features and the power capability of the latest
CoolSET device ICE2B765P of the second generation of CoolSET in a TO220 package with
extended creepage distance for higher electrical strength and isolated tab.
CoolSET
CoolSET is a current mode control IC and the power MOSFET CoolMOS within one standard
package designed for low cost power supplies. CoolSET combines the superior technology of
CoolMOS and the optimized technology of the control IC with enhanced protection features and
improved standby power concept. The integrated propagation delay compensation (patented by
Infineon Technologies) prevents a current overshoot, the result is a reduced electrical stress on the
MOSFET, the transformer and the output diode. The 650V / 800V high avalanche rugged CoolMOS
eliminates or reduces the need for a heatsink and permits a SMPS design with a simple RCD snubber
and a low cost standard transformer design. The lowest area specific Rdson leads to a high efficiency
and permits an operation at high ambient temperature. CoolSET permits always a safety operation
during any error cases due to the integrated protection features.

This document contains the power supply specification, schematic, bill of material and the transformer
construction documentation. Typical operating characteristics are presented at the rear of the report
and consist of performance curves and scope waveforms.
Note:
Design calculations for the components and the transformer were performed in accordance with the
application note “AN–SMPS–ICE2AXXX for OFF – Line Switch Mode Power Supplies” and
FlyCal, a EXCEL based design software according to the application note AN-SMPS-ICE2AXXX. The
application note and FlyCal are available on the Internet: www.Infineon.com/CoolSET
