DKPower DK910 10W Primary‑Side Feedback AC‑DC Converter Chip Datasheet
The DK910 is a primary‑side feedback AC‑DC switching regulator chip designed for 10 W output power. It integrates a 700 V high‑voltage MOSFET, peak‑current detection, PWM oscillator with spread‑frequency, and multiple protection functions such as over‑temperature, over‑current, over‑voltage, and short‑circuit protection. The chip operates from a wide input voltage range of 85 V to 265 V and requires few external components, simplifying transformer design.
Typical applications include LED power supplies, adapters, and small household appliances such as microwave ovens, air conditioners, DVD players, and set‑top boxes. The pinout consists of eight pins (IS, GND, FB, VCC, OC, etc.) providing functions for current setting, grounding, feedback, supply, and MOSFET drain connections. Package options are SOP‑8 with dimensions shown in the datasheet. This manual is written in Chinese.
