MP2364DF-LF-Z

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.

Direct exact equivalents depend on package/pinout and specs. MP2364DF-LF-Z is a Monolithic Power Systems 3A, high‑voltage buck regulator (input up to ~42V, adjustable output). For a cross‑reference, use MPS’s cross‑reference tool or distributor databases; similar 3A buck regulators from TI, Analog Devices, On Semiconductor, etc., may work if they match your input range, output voltage, current, switching frequency, and footprint. Please provide input range, output voltage, current, and package for precise substitutes.

- Pin count: 8 pins (DFN-8 package).
- Function: High-efficiency buck (step-down) DC-DC converter with an integrated switch and regulation circuitry. It uses a feedback pin to set the output voltage and includes enable/soft-start and other control pins to regulate a higher input voltage to a lower, stable output.

- Manufacturer: Monolithic Power Systems, Inc. (MPS)
- What kind of company: A fabless semiconductor company that designs and sells high-performance power-management ICs, including DC-DC converters, controllers, and PMICs for various applications.

MP2364DF-LF-Z is a high-efficiency synchronous buck regulator. Typical application areas:
