Datasheet

NCP3170ADR2G – Buck Switching Regulator IC 3A SOIC-8

The NCP3170ADR2G from onsemi is a high-performance, versatile 3A synchronous step-down (buck) switching regulator designed for industrial, communication, and embedded power supply systems. Operating across a wide input voltage range of 4.5V to 18V, it delivers excellent efficiency, compact design, and robust reliability for applications requiring stable DC-DC conversion. Featuring current-mode PWM control, the NCP3170A offers fast transient response, precise voltage regulation, and the flexibility to balance performance and component size through adjustable frequency operation. The device’s integrated 3A low-side and high-side MOSFETs minimize external component count while delivering superior efficiency and thermal performance. With its programmable switching frequency (150kHz to 1MHz), designers can optimize the trade-off between efficiency and size. The device includes internal soft-start, cycle-by-cycle current limiting, short-circuit protection, thermal shutdown, and under-voltage lockout (UVLO)—ensuring safe and reliable operation under all conditions. Its synchronization capability allows multiple regulators to operate in phase, minimizing system noise.

Key Features:

  • Wide Input Voltage Range: 4.5V to 18V for flexible system compatibility.
  • 3A Continuous Output Current: Integrated MOSFETs for efficient power delivery.
  • High Efficiency Design: Optimized for low power loss and superior thermal performance.
  • Adjustable Switching Frequency: 150kHz to 1MHz for size and efficiency optimization.
  • Current-Mode PWM Control: Fast transient response and stable operation across loads.
  • Synchronization Function: Supports external clock synchronization for EMI reduction.
  • Internal Soft-Start: Prevents inrush current and enables controlled startup.
  • Comprehensive Protection: Includes OCP, SCP, UVLO, and thermal shutdown protection.
  • Compact Package: SOIC-8 design for easy PCB layout and efficient heat dissipation.
  • Applications: Ideal for FPGAs, microcontrollers, industrial controllers, communication equipment, and embedded systems.
