Switching frequency1000 kHz
Output 15 V / 3 A
IC revision2

Description

The NCP3170 is a flexible synchronous PWM Switching Buck Regulator. The NCP3170 operates from 4.5 V to 18 V, producing up to 3 A and is capable of producing output voltages as low as 0.8 V. The NCP3170 also incorporates current mode control. To reduce the number of external components, a number of features are internally set including soft start, power good detection, and switching frequency. The NCP3170 is currently available in an SOIC-8 package.

Features

  • 4.5 V to 18 V Operating Input Voltage Range
  • 90mΩ High-Side, 24mΩ Low-Side MOSFET
  • Output Voltage Adjustable to 0.8 V
  • 3 A Continuous Output Current
  • Fixed 500 kHz and 1 MHz PWM Operation
  • 1.5% Initial Output Accuracy
  • Internal 4 ms SoftStart
  • ShortCircuit Protection
  • Thermal Shutdown
  • Light Load Efficiency
  • Dedicated PowerGood and ENABLE pin

Typical applications

  • Point of Load (POL) DC/DC Regulator
  • Set-Top-Box (STB)
