概要
Description
MP2364DF-LF-Z is a Monolithic Power Systems high-efficiency buck (step-down) DC-DC regulator. It integrates the power switch and control circuitry to convert a higher input voltage to a regulated lower output. Key points:
- Wide input range (up to about 40 V) with up to ~4 A output capability.
- Output voltage set via external feedback divider.
- Fixed switching frequency with soft-start, enable control, and protections (current limit, thermal shutdown, UVLO/OVP).
- LF-Z indicates lead-free, RoHS-compliant packaging in a compact DFN/QFN-style package.
Typical external components: inductor, input/output capacitors, and a catch diode (for non-synchronous designs) or an additional MOSFET for synchronous operation.
Applications: point-of-load supplies for automotive, telecom, industrial, and consumer electronics.
Note: For exact specs, pinout, and recommended application circuits, consult the official MP2364DF-LF-Z datasheet.
