Overview
Description
The RT8175AGQW is a synchronous step-down DC-DC converter from Richtek, designed for high-efficiency power conversion in compact applications.
### Key Features:
- Input Voltage: 4.5V–18V
- Output Current: Up to 3A
- Switching Frequency: 600kHz (adjustable)
- Efficiency: Up to 95% (PWM mode)
- Protections: Over-current (OCP), over-voltage (OVP), thermal shutdown (OTP)
- Package: WDFN-10 (3x3mm)
### Applications:
- Notebooks, tablets, SSDs
- Industrial & embedded systems
- Point-of-load (POL) power supplies
The RT8175AGQW supports PWM/PFM modes for optimized efficiency across loads and integrates low-RDS(ON) MOSFETs for reduced power loss. Its small form factor makes it ideal for space-constrained designs.
For detailed specs, refer to the Richtek datasheet.
