Nowadays, Power devices defined as innovative technology enabling future development of power converters and systems. These Power Device IC capable of precisely controlling electrical energy from the source to the load according to the load demand, at high efficiency, and with outstanding reliability. A power device IC designed as a semiconductor device acts as a switch in power electronics (ex: switch-mode power supply). Such a type of device known as the power device. Or when used in an integrated circuit, referred to as the power IC.
The 5L0380 Power Switch IC designed as an integrated Pulse Width Modulators (PWM) and Sense FETs designed explicitly for high-performance offline Switch Mode Power Supplies (SMPS) operated with minimal external components. Both devices integrated as high voltage power switching regulators which combine an avalanche rugged Sense FET with a current mode PWM control block. This integrated PWM controller consists of a fixed oscillator with frequency modulation for reduced EMI. It features Under Voltage Lock Out (UVLO) protection, Leading Edge Blanking (LEB). And also optimized gate turn-on/turn-off driver, Thermal Shut Down (TSD) protection, Abnormal Over Current Protection (AOCP).
Meanwhile, it also offers temperature compensated precision current sources for loop compensation and fault protection circuitry. 5L0380 Power Switch IC contains all the functions required to design a power supply circuit. Comparing with the discrete MOSFET and PWM controller solution, it reduces overall system cost, components number, size and weight. At the sametime, it increases the efficiency, productivity and offers high reliability for the device. 5L0380 is the perfect basic platform for the cost-effective design of flyback convertors.
