MP2635AGR-Z

MP2635AGR-Z is a Monolithic Power Systems DC-DC buck regulator. It integrates the high-side switch and control circuitry to convert a higher input voltage into a stable lower output for portable electronics. Key points:
- Adjustable output via external feedback network (with fixed-output variants available)
- Current-mode PWM control for fast, stable regulation
- Protections: undervoltage lockout, overcurrent/short-circuit protection, and thermal shutdown
- Soft-start and enable/shutdown control
- Packaging: RoHS-compliant, tape-and-reel (-Z)
Typical applications: point-of-load regulators for CPUs/FPGA/memory, microcontrollers, and other battery-powered devices where compact size and high efficiency are important. For exact electrical characteristics, pinout, and operating conditions, refer to the MP2635AGR-Z datasheet.

Here are the key features of MP2635AGR-Z (Monolithic Power Systems):
- High-efficiency synchronous buck regulator with integrated high-side and low-side MOSFETs
- Wide input voltage range suitable for automotive/industrial use
- Adjustable output via external feedback network
- Fixed-frequency PWM operation with auto switch between PWM/PFM for light-load efficiency
- Enable/shutdown control and programmable soft-start
- Protection features: overcurrent/short-circuit, overvoltage, and thermal shutdown
- Low quiescent current for good standby and light-load performance
- Small 8-pin package (AGR-Z variant), RoHS-compliant
- Suitable for point-of-load and VRM-type applications
Note: Specific numbers (e.g., maximum output current, exact input range, switching frequency) vary by variant; consult the datasheet for exact specs.

- Pin count: 8 pins
- Function: A single-channel, high-efficiency synchronous buck (step-down) DC-DC regulator with integrated MOSFETs. It converts a higher input voltage to a regulated output using feedback (FB) and is controlled by an enable input (EN). It uses a BST/bootstrap node for gate drive and provides protection features (overcurrent, thermal shutdown). Typical pins include VIN, GND, SW (switch node), BST, FB, EN, and related ground/reference pins.

- Manufacturer: Monolithic Power Systems, Inc. (MPS)
- Company type: A fabless semiconductor company that designs and markets high-performance power management ICs (e.g., DC-DC converters, LED drivers, PMICs) for consumer, automotive, and industrial applications; fabrication is done through external foundries.

MP2635AGR-Z is a high-efficiency buck regulator used for voltage regulation in compact power supplies. Common application areas include:
- VRMs for CPUs/GPUs/FPGA/ASICs in desktops, servers, and embedded systems
- Portable and battery-powered devices (phones, tablets, cameras, wearables)
- Telecom and networking equipment power rails
- Automotive and industrial control electronics
- Consumer electronics such as set-top boxes, printers, and multimedia appliances
