TopologyBuck Converter
Input voltage4.5-28 V
Output 113 V / 10 A
IC revision00

Description

The TPS56A37 is a high-efficiency, easy-to-use, synchronous buck converter with a wide input voltagerange of 4.5V to 28V. The device supports up to 10A continuous output current at output voltages between 0.6V and 13V.The TPS56A37 uses D-CAP3 control mode to provide fast transient response, good line and load regulation, no requirement for external compensation, and supports low equivalent series resistance (ESR) output capacitors like MLCC.

Features

  • 4.5V to 28V input voltage range
  • 0.6V to 13V output voltage range

  • Integrated 19.4mΩ and 8.5mΩ MOSFETs
  • 0.6V ±1% reference voltage at 25°C
  • 45uA low quiescent current
  • D-CAP3™ control mode for fast transient response
  • Eco-mode (auto-skip mode) for high light-load efficiency
  • Fixed 500kHz switching frequency
  • Cycle by cycle over current limit
  • Adjustable soft-start time with default 1.8ms
  • Built-in output discharge function
  • Power-good indicator to monitor output voltage
  • Supports up to 98% duty operation
  • Non-latched protections for UV, OV, OT, and UVLO
  • –40°C to +150°C operating junction temperature
  • Small 10-pin 3.0mm × 3.0mm HotRod™ QFN package
  • Pin-to-pin compatible with 6A TPS56637 and 8A TPS56837

Typical applications

  • Industrial PC, EPOS, factory automation and control
  • General purposes for 12V,19V, 24V power-bus supply
  • Monitors, TV, speakers, PC and notebooks, portable electronics
  • Multifunction printers, video conference system
