Description

The NCP1599 is a fixed 1 MHz, high−output−current, synchronous PWM converter that integrates a low−resistance, high−side P−channel MOSFET and a low−side N−channel MOSFET. The NCP1599 utilizes internally compensated current mode control to provide good transient response, ease of implementation, and excellent loop stability.The NCP1599 includes an internally fixed switching frequency (FSW), and an internal soft−start to limit inrush current.Other features include cycle−by−cycle current limiting,short−circuit protection, power saving mode and thermal shutdown.

Features

  • Internal 140 mΩ High−Side P−Channel and 90 mΩ Low−SideN−Channel MOSFET
  • Fixed 1 MHz Switching Frequency
  • Cycle−by−Cycle Current Limiting
  • Hiccup Mode Short−Circuit Protection
  • Overtemperature Protection
  • Internal Soft−Start
  • Start−up with Pre−Biased Output Load
  • Adjustable Output Voltage Down to 0.8 V
  • Power Saving Mode During Light Load
  • These are Pb−Free Devices

Typical applications

  • Networking Equipment
  • LCD TV
  • Wireless and DSL/Cable Modem
  • Hard Disk Drivers
  • Set−Top Boxes
  • DSP Power
  • Home Audio
  • Computer Peripherals
  • USB Power Devices
