Description

NCP1592 is a low input voltage 6 A synchronous buck converter that integrates both 30 m high side and low side MOSFETs.NCP1592 is designed for space sensitive and high efficiency applications. The main features include: a high performance voltage error amplifier; an under−voltage−lockout circuit to prevent start−up until the input voltage reaches 3 V; an internally or externally programmable soft−start circuit to limit inrush currents; and a power good output monitor signal. NCP1592 is available in thermally enhanced 28−pin TSSOP package.

Features

  • 30 m, 12 A Peak MOSFET Switches for High to Efficiency at 6 A-Continuous Output Source or Sink Current
  • Adjustable Output Voltage Down to 0.891 V With 1.0% Accuracy
  • Wide PWM Frequency: Fixed 350 kHz, 550 kHz or Adjustable280 kHz to 700 kHz
  • Synchronizable to 700 kHz
  • Load Protected by Peak Current Limit and Thermal Shutdown
  • Integrated Solution Reduces Board Area and Component Count
  • This is a Pb−Free Device

Typical applications

  • Low−Voltage, High−Density Distributed Power Systems
  • Broadband, Networking and Optical Communications Infrastructure
  • Portable Computing/Notebook PCs
  • High Performance Point of Load Regulation for DSPs, FPGAs, ASICs and Microprocessors
