EUP3484DIR1

EUP3484DIR1 is a high-efficiency, synchronous step-down DC-DC converter from Richtek. It operates at a fixed 340kHz switching frequency and supports an input voltage range of 4.5V to 18V, delivering up to 3A of output current. Key features include:
- High Efficiency: Uses synchronous rectification for minimal power loss.
- Compact Design: Available in a small SOP-8 package.
- Protections: Over-current (OCP), over-temperature (OTP), and under-voltage lockout (UVLO).
- Adjustable Output: Configurable via external resistors (0.8V to 15V).
Ideal for industrial, consumer, and networking applications requiring stable power conversion. Its low standby current (<1µA) enhances energy efficiency in battery-powered systems.
