Beschreibung

This engineering report is a 60 W 12 V and 5 V demo board designed in a QR Flyback converter topology using the fifth-generation QR controller ICE5QSAG and a P7 series of HV CoolMOS™ IPA80R600P7. The target applications of ICE5QSAG are either auxiliary power supplies for white goods, PCs, servers and TVs, or enclosed adapters for Blu-ray players, set-top boxes, games consoles, etc. The new improved digital frequency reduction with proprietary QR operation offers lower EMI and higher efficiency for a wide AC range by reducing the switching frequency difference between low- and high-line. The enhanced Active Burst Mode (ABM) power enables flexibility in standby power operation range selection and QR operation during ABM. As a result, the system efficiency, over the entire load range, is significantly improved compared to conventional free-running QR converters implemented with only maximum switching frequency limitation at light load. In addition, numerous adjustable protection functions have been implemented in ICE5QSAG to protect the system and customize the IC for the chosen application. In case of failure modes like brown-out or line Over Voltage (OV), VCC OV/Under Voltage (UV), open control-loop or over-load, output OV, over-temperature, VCC short-to-GND and CS short-to-GND, the device enters protection mode. By means of the cycle-by-cycle Peak Current Limitation, the dimensions of the transformer and the current rating of the secondary diode can both be optimized. In this way, a cost-effective solution can easily be achieved.
