TPS5402 - NON-SYNCHRONOUS STEP-DOWN REGULATOR

General Description

The TPS5402 is a monolithic non-synchronous buck regulator with wide operating input voltage range from 3.5 V to 28 V.

Current mode control with internal slope compensation is implemented to reduce component count.

Key Features

  • 1.
  • 3.5-V to 28-V Wide Input Voltage Range.
  • Up to 1.7-A Maximum Continuous Output Loading Current.
  • Pulse Skipping Mode to Achieve High Light Load Efficiency.
  • High Light Load Efficiency.
  • Frequency Spread Spectrum to Reduce EMI.
  • Adjustable 50-kHz to 1.1-MHz Switching Frequency Set by an External Resistor (Leave pin ROSC floating. Set frequency to 120 kHz and ground connection to 70 kHz).
  • Frequency Spread Spectrum to Ease EMI Issue.
