概述

Description

NCP5183DR2G is an ON Semiconductor buck (step-down) switching regulator IC. It is used to convert a higher input voltage into a stable, lower output for microprocessors, microcontrollers, and other loads, often in automotive and industrial applications. The DR2G package denotes a compact RoHS SMD package.
Key points:
- Regulation: PWM switching regulator with an external inductor and energy storage components.
- Output: adjustable via a feedback resistor divider (and may have a fixed option depending on variant); controlled by an enable/soft-start mechanism.
- Protection: overcurrent/short-circuit protection and thermal shutdown.
- Efficiency: designed for high efficiency across load conditions.
- External components: requires inductor, catch diode (if not using a synchronous design), input/output capacitors, and feedback network.
- Applications: power supplies for PMICs, MCU rails, automotive and industrial electronics.
For exact electrical specifications (input range, output range, switching frequency, current capability) and schematic/app notes, consult the NCP5183DR2G datasheet and product page.

Features

NCP5183DR2G features (On Semiconductor) typically include:
- High-efficiency buck DC-DC converter with integrated high-side MOSFET
- Wide input voltage range (suitable for various apps)
- Adjustable output via external resistor divider
- Fixed switching frequency with current‑mode PWM control (and PWM/PFM modes)
- Soft-start to limit inrush
- Enable/disable control
- Overcurrent/short-circuit protection
- Thermal shutdown and thermal overload protection
- UVLO (undervoltage lockout) protection
- Optional protection features (e.g., overvoltage)
- Pin-compatible, compact DR2G package
Note: exact electrical specs (input range, output range, frequency, efficiency) vary by variant. Please consult the NCP5183DR2G datasheet for precise data.

Package
