HIGH FREQUENCY SECONDARY RECTIFIERS
PRELIMINARY DATASHEET
MAJOR PRODUCTS CHARACTERISTICS IF(AV) VRRM VF (max) trr (max) FEATURES AND BENEFITS COMBINES HIGHEST RECOVERY AND VOLTAGE PERFORMANCE. ULTRA-FAST, SOFT AND NOISE-FREE RECOVERY FOR LOW SIDE EFFECTS. HIGH OPERATING TEMPERATURE THANKS TO LOW LEAKAGECURRENT. DESCRIPTION Dual rectifiers suited for Switch Mode Power Supply and high frequency DC to DC converters. Packaged in Max247, this device is intended for use in low voltage, high frequency inverters, free wheeling operation, welding equipments and telecom power supplies.
