The Power Integrations TOP243PN is an integrated offline switcher IC belonging to the TOPSwitch-GX family. It utilizes a flyback topology and is housed in an 8-PDIP-B package, suitable for through-hole mounting.
This device offers a voltage rating of 700V and can deliver up to 25W of power. Its operating frequency ranges from 66kHz to 132kHz, with features like frequency jittering to reduce EMI and a half-frequency option for video applications. The TOP243PN includes integrated fault protection for current limiting, over-temperature, and over-voltage conditions.
Key design features include an externally programmable current limit, integrated soft-start, and line under-voltage/over-voltage detection. The device is designed for energy efficiency, with low consumption in remote off modes and frequency adjustment based on load for high standby efficiency. It regulates to zero load without requiring a dummy load.
The operating temperature range is -40°C to 150°C (TJ). The TOPSwitch-GX family integrates the high-voltage power MOSFET, PWM control, and fault protection onto a single CMOS chip, reducing system cost and improving design flexibility.
