The TOPSwitch‑HX series provides an integrated offline switch controller with EcoSmart® efficiency, low thermal resistance and a thin eSIP package for space‑constrained adapters. It combines a high‑voltage MOSFET, PWM controller, oscillator, soft‑start, over‑voltage, under‑voltage and thermal‑shutdown protection in a single chip.
The document details pin functions, operating modes, switching frequency options (66 kHz or 132 kHz), programmable current limit, and provides extensive electrical specifications, package drawings and ordering information for the TOP252‑262 product range. This manual is written in Chinese.
| Maximum Output Power | 35 W (continuous) / 48 W (peak at 230 VAC) |
|---|---|
| Switching Frequency (default) | 132 kHz (66 kHz when F‑pin tied to control) |
| Maximum Duty Cycle (DCMAX) | 78 % |
The default switching frequency is 132 kHz; it drops to 66 kHz when the frequency pin is tied to the control pin.
Yes, the output over‑voltage protection (OVP) can be programmed by the user for latch or non‑latch operation.
Available packages are P (DIP‑8C), G (SMD‑8C), M (SDIP‑10C), Y (TO‑220‑7C), E (eSIP‑7C) and L (eSIP‑7F).
