概要
Description
MP5017GD-Z is a high-efficiency synchronous buck regulator from Monolithic Power Systems. It converts a higher DC input to a lower, regulated output rail used for processor cores, memory, FPGAs, and other point‑of‑load applications. The device integrates the main switching MOSFETs and control circuitry, typically using current‑mode PWM and an external feedback network to set the output voltage. It includes protections such as over‑current, over‑temperature, and undervoltage, along with an enable/shutdown control and soft‑start to limit inrush. The GD‑Z suffix indicates a RoHS‑compliant, lead‑free (green) package. Common applications include VRMs for CPUs/GPUs, telecom/industrial DC‑DC rails, and other system power supplies. For exact electrical specs, pinout, and recommended external components, consult the official MP5017GD‑Z datasheet.
Features
Here are the typical features of MP5017GD-Z (Monolithic Power Systems):
- Wide input range up to 60V
- Synchronous buck regulator with integrated high-side and low-side MOSFETs
- Output current capability in the amp range (commonly up to ~4A)
- Adjustable output via external feedback resistors
- Current-mode PWM control for fast transient response
- Soft-start and enable/shutdown control
