TPS62480 - 2.4-V to 5.5-V 6-A 2-Phase Step-Down Converter

Description

The TPS62480 is a synchronous 2-phase step-down DC-DC converter for low profile point-of-load power supplies.

The input voltage range of 2.4 to 5.5 V enables operation from typical 3.3-V or 5-V interface supplies as well as from backup circuits dropping down as low as 2.4 V.

Features

  • 1 Dual Phase Current Mode Topology.
  • Input Voltage Range 2.4 to 5.5 V.
  • Output Voltage Range 0.6 to 5.5 V.
  • Output Current of 6 A.
  • Typical Quiescent Current of 23 µA.
  • Feedback Voltage Accuracy of ±1% (PWM Mode).
  • Output Voltage Select.
  • Phase Shifted Operation.
  • Automatic Power Save Modes.
  • Forced PWM Mode.
  • Adjustable Soft Start.
  • Power Good / Thermal Good Outputs.
  • Undervoltage Lockout.
