The SP6606 is a high‑performance, low‑power switch‑mode power‑supply controller with built‑in MOSFET, multiple protections and a 55 kHz fixed switching…
The SP6606 is a current‑mode PWM controller designed for offline switch‑mode power supplies up to 27 W. It integrates a 650 V power MOSFET, low‑standby power (<100 mW), and features such as soft‑start, leading‑edge blanking, and internal slope compensation.
The device operates over a wide input range (85 V‑265 V) and includes comprehensive protection functions (OCP, OLP, OVP, UVLO, OTP). It is supplied in a lead‑free DIP‑8 package and runs at a fixed 55 kHz switching frequency, with optional jitter and spread‑spectrum modes to improve EMI performance.

| Input voltage range | 85 V‑265 V |
|---|---|
| Integrated MOSFET voltage rating | 650 V |
| Typical startup current (VDD=11 V) | 20 µA |
| Maximum output power | 27 W |
| Package | DIP‑8 lead‑free |
| Standby power consumption | <100 mW |
| Leading‑edge blanking time | 270 ns |
The device operates from 85 V to 265 V input voltage.
It includes over‑current (OCP), overload (OLP), over‑voltage (OVP), undervoltage lock‑out (UVLO), and over‑temperature (OTP) protections.
Typical startup current is about 20 µA when VDD is 11 V.
