The TOP248 is a highly integrated, monolithic off-line switcher IC designed for use in low-power offline flyback converters. Manufactured by Power Integrations, it incorporates a 700 V power MOSFET, high-voltage switched current source, and current-mode PWM control circuitry into a single chip.
Power supplies are an important part of any electronic system. Even though there are multiple categorizations within the power supplies, we are going to look into the AC- DC converters, that are used in mains powered equipment and appliances.
Vishay Intertechnology, Inc has introduced a new fourth-generation 600 V EF Series fast body diode MOSFET in the low-profile PowerPAK 10 x 12 package that provides high efficiency and power density for telecom, industrial, and computing applications.
onsemi has announced the new TO-Leadless (TOLL) packaged silicon carbide (SiC) MOSFET that addresses the rapidly growing need for high-performance switching devices which are suitable for designs with high levels of power density.
