概要
Description
MP2208DL-LF-Z is a high-efficiency synchronous buck regulator IC from Monolithic Power Systems. It combines a PWM controller with high- and low-side switches to step a higher input voltage down to a lower, regulated output.
Key points
- Wide input range, adjustable output via external resistor network.
- Current‑mode control with soft-start, enable/shutdown, and protection features (over-current, thermal).
- High efficiency and suitable for compact, high‑density power boards.
- Package: 8-pin lead-free (DL-LF-Z family, surface-mount).
Typical use
- Point‑of‑load regulators for microcontrollers/FPGA, sensors, and other DC‑DC conversion needs in portable, automotive, and industrial electronics.
Note
- For exact electrical specs (input range, output current, switching frequency, external components), consult the official MP2208DL-LF-Z datasheet.
