RT9085AWSC

RT9085AWSC is a Richtek DC-DC buck regulator (part of the RT9085 family) used to generate a stable supply rail in portable electronics. It’s a compact power-management IC that converts a higher input voltage (typical Li‑ion range) down to a user-selectable output via an external resistor network. Key features usually include adjustable output, a high-efficiency switching buck topology, enable/shutdown control, and protections such as overcurrent, thermal shutdown, and undervoltage lockout. The AWSC suffix indicates a small, lead-free 8-pin package with an exposed pad for thermal performance. Common applications are smartphones, wearables, IoT sensors, and other battery-powered devices needing a single-supply regulator. For exact specs (input range, switching frequency, allowable output voltages, pinout), consult the official RT9085AWSC datasheet.

Pin count: 8 pins.
Function: A synchronous buck DC-DC regulator (step-down converter) in an 8-pin package, used to convert a higher input voltage to a regulated lower output voltage (with typical VIN, SW, GND, EN, FB, etc.).

- Manufacturer: RichTek Technology Corp. (Richtek)
- What kind of company: A Taiwanese semiconductor company that designs and markets analog and power-management ICs (PMICs, DC-DC converters, LED drivers, etc.).
