Description
RT9173CGSP is a Richtek DC-DC buck regulator packaged in the CGSP form factor. It’s designed to convert a higher input voltage down to a stable, lower output rail for portable and embedded electronics.
Key points:
- Switching regulator with integrated control logic; output voltage is set via external feedback (fixed or adjustable versions).
- Includes enable/soft-start, overcurrent protection, UVLO/thermal protection.
- Requires external components: inductor, input/output capacitors; may use a catch diode if operated in asynchronous mode (or a synchronous design if supported).
- Typical applications: power rails for microcontrollers, processors, memory, sensors in mobile/embedded devices.
- For exact specs (input range, output options, current capability, pinout), consult the RT9173 datasheet and the CGSP packaging details.
