TPS54310 - 3-A Output Synchronous-Buck PWM Switcher

General Description

As a member of one of TI's families of dc/dc regulators, the TPS54310 low-input-voltage highoutput-current synchronous-buck PWM converter integrates all required active components.

Key Features

  • 1 60-mΩ MOSFET switches for high efficiency at 3A continuous output source or sink current.
  • Adjustable output voltage down to 0.9 V With 1% accuracy.
  • Externally compensated for design flexibility.
  • Fast transient response.
  • Wide PWM frequency: fixed 350 kHz, 550 kHz, or adjustable 280 kHz to 700 kHz.
  • Load protected by peak current limit and thermal shutdown.
  • Integrated solution reduces board area and total cost 2.
