30W 16V Demoboard using ICE3BR0665J
1 Abstract
This document is an engineering report of a universal input 30W 16V off line fly back converter power supply
utilizing IFX F3R CoolSET®1 ICE3BR0665J. The application demo board is operated in Discontinuous
Conduction Mode (DCM) and is running at 65 kHz switching frequency. It has a one output voltage with
secondary side control regulation. It is especially suitable for small power supply such as DVD player, set-top
box, game console, charger and auxiliary power of high power system, etc. The ICE3BR0665J is the latest
version of the CoolSET®. Besides having the basic features of the F3R CoolSET® such as Active Burst
Mode, propagation delay compensation, soft gate drive, auto restart protection for serious fault (Vcc over
voltage, Vcc under voltage, over temperature, over-load, open loop and short opto-coupler), it also has the
BiCMOS technology design, built-in soft start time, built-in and extendable blanking time, frequency jitter
feature with built-in jitter period and external auto-restart enable, etc. The particular features needs to be
stressed are the best in class low standby power and the good EMI performance.

This document contains the list of features, the power supply specification, schematic, bill of material and the
transformer construction documentation. Typical operating characteristics such as performance curve and
scope waveforms are showed at the rear of the report.
1 CoolSET® is a trade mark of Infineon which is a PWM control IC integrated with CoolMOS® in one package.

N.B. : In order to get the optimized performance of the CoolSET®, the grounding of the PCB layout must be
connected very carefully. From the circuit diagram above, it indicates that the grounding for the
CoolSET® can be split into several groups; signal ground, Vcc ground, Current sense resistor ground
and EMI return ground. All the split grounds should be connected to the bulk capacitor ground
separately.
• Signal ground includes all small signal grounds connecting to the CoolSET® GND pin such as filter
capacitor ground, C7, C8, C9 and opto-coupler ground.
• Vcc ground includes the Vcc capacitor ground, C6 and the auxiliary winding ground, pin 2 of the
power transformer.
• Current Sense resistor ground includes current sense resistor R5 and R5A.
• EMI return ground includes Y capacitor, C5.
