The PN8147T integrates a PWM controller and power MOSFET for high‑performance, component‑reduced AC/DC switching power supplies. It provides comprehensive protection features such as cycle‑adjustable over‑current, overload, over‑voltage, CS short‑circuit, and soft‑start, and supports Hi‑mode, Eco‑mode, and Burst‑mode power‑adjustment.
Designed for ultra‑low standby consumption (<50 mW at 230 VAC) and optimal efficiency across 85‑265 V AC, the chip includes an internal high‑voltage start‑up module and frequency‑modulation technology for good EMI performance. Typical applications include switch‑mode adapters, battery chargers, white‑goods auxiliary supplies, and smart meters. This manual is written in Chinese.
| Input voltage range | 85~265 V AC |
|---|---|
| Standby power consumption | < 50 mW @230VAC |
| Soft‑start time | 8.5 ms |
| Over‑temperature protection temperature | 135‑150 °C |
The standby power consumption is less than 50 mW at 230 VAC.
