MP2364DF-LF-Z

MP2364DF-LF-Z is Monolithic Power Systems’ synchronous buck DC-DC regulator. It combines the high-side and low-side MOSFETs and provides a low-voltage, adjustable output from a higher input voltage.
Key points:
- Wide input range and high efficiency: suitable for automotive and telecom power rails.
- Synchronous buck with current-mode PWM; no external Schottky diode required.
- Adjustable output via external resistor divider; programmable enable, soft-start, and protection features (OC/UVLO/thermal shutdown).
- Package: LF-Z indicates lead-free, RoHS-compliant, tape-and-reel/DFN-type packaging (industrial-ready).
- Applications: converting 9–36V (or similar) to 5V/3.3V/other rails for processors, FPGA, memory, and other DC-DC needs.
Design notes:
- External components: input/output capacitors, inductor, feedback divider, possible compensation network.
- Follow datasheet layout recommendations to ensure stability and performance.
For exact electrical specs, pinout, and application guidelines, consult the MP2364DF-LF-Z datasheet.

Here are the main features of MP2364DF-LF-Z (concise):
- 4A step-down (buck) converter with integrated high-side switch
- Wide input range suitable for 4.5V to ~42V applications
- Adjustable output via external feedback network (ref ~0.8V)
- Fixed-frequency PWM control with good line/load regulation and soft-start
- Protection: overcurrent/short-circuit, over-temperature, undervoltage lockout, and output over-voltage protection
- Enable/shutdown control for power sequencing
- High efficiency and low quiescent current
- Compact RoHS-compliant 8-pin package (lead-free DFN/SOP variant)
Note: For exact electrical specifications (voltage ranges, efficiency, timing, and pinout), please refer to the official datasheet.

The MP2364DF-LF-Z is supplied in a 10-pin DFN package (3.0 mm × 3.0 mm), lead‑free (LF), tape‑and‑reel (Z).

The MP2364DF-LF-Z is supplied in an 8-pin DFN package with an exposed thermal/ground pad. It is a synchronous step‑down (buck) switching regulator. Typical pin functions (see datasheet for exact pin numbering) are:
- VIN: input supply
- SW: switch/node (connection to inductor)
- BST: bootstrap for high-side MOSFET gate drive
- EN (or ON/OFF): enable/shutdown control
- FB: feedback for output-voltage regulation
- GND/PGND and exposed pad: ground/thermal return
- One or more control/compensation pins (mode/soft‑start/COMP) for loop compensation and configuration
Refer to the MP2364 datasheet for the precise pin map and recommended PCB land pattern.

The MP2364DF-LF-Z is manufactured by Monolithic Power Systems (MPS). MPS is a fabless semiconductor company headquartered in San Jose, California, that designs and supplies power-management integrated circuits and analog/mixed-signal solutions (switching regulators, PMICs, LED drivers, power modules) for consumer, computing, industrial, telecom and automotive markets.

MP2364DF-LF-Z is a high-efficiency synchronous buck regulator. Typical applications:
- Automotive and industrial DC–DC power modules
- Consumer electronics and embedded systems (core rails for processors/SoCs and memory)
- Telecom and networking equipment
- Battery-powered handheld devices and portable accessories
- Power supplies for monitors/TVs and set-top boxes
- General on-board step-down regulators in wide-range input environments

Direct equivalents are other MP2364 family variants: MP2364 (base), MP2364DF, MP2364DF-LF, MP2364DN and MP2364DN-LF-Z (package/suffix variants). For third‑party “equivalents,” choose a 2A synchronous buck regulator with the same VIN range, switching frequency and pinout — verify pin‑to‑pin compatibility on datasheets before substituting.
