TOP210PN Offline PWM Switch 5.8V 1.2mA IC DIP-8

From the shop's description

TOP210PN Offline PWM Switch 5.8V 1.2mA IC DIP-8 The TOP210PN is a member of the TOPSwitch family, integrating a high-voltage power MOSFET with a PWM controller and control circuitry into a single DIP-8 package. It is specifically designed to simplify the design of switch-mode power supplies (SMPS) by minimizing the number of external components required, reducing both cost and circuit complexity. This IC operates directly from rectified AC mains and is typically used in flyback converter topologies. It provides stable and efficient power conversion with built-in protection mechanisms such as thermal shutdown, current limiting, and auto-restart. Due to its reliability and compact integration, the TOP210PN is widely used in low-power applications across consumer and industrial electronics. Features: Integrated high-voltage power MOSFET. Built-in PWM controller. Internal oscillator. Reduced external component count. Auto-restart protection. Thermal shutdown protection. Current limiting protection. High efficiency operation.
