Power Integrations TOP242-250 Product Manual
The TOP242‑250 series (TOPSwitch‑GX) integrates a high‑voltage MOSFET, PWM controller and protection circuitry on a single silicon die. It offers higher output power, reduced component count, and flexible design options such as external current‑limit programming and line‑voltage detection. The device operates at a default switching frequency of 132 kHz with a typical maximum duty cycle of 78 %.
The manual provides detailed pin descriptions, functional block diagrams, and application examples for various power‑supply topologies. It also explains soft‑start, automatic restart, thermal shutdown, UV/OV protection, and remote on/off control, helping designers implement efficient and reliable offline power supplies.
