TPS54A20 - Step Down Converter

Description

The TPS54A20 is a two-phase, synchronous series capacitor buck converter designed for small size, low voltage applications from a 12-V input rail.

This topology uniquely merges a switched capacitor circuit with a two phase buck converter.

Features

  • 1 Two-phase, Synchronous Series Capacitor Buck Converter.
  • Automatic Current Balancing Between Phases.
  • 2-MHz to 5-MHz Per Phase Switching Frequency.
  • 14-ns Minimum On-Time.
  • 0.51-V to 2-V Output Voltage Range with ±0.5% Feedback Reference Voltage.
  • Input Overvoltage Lockout for 17-V Surge Protection.
  • Adjustable Current Limit with Auto Restart (Hiccup).
  • Synchronizes to an External Clock.
  • Fixed Frequency in Steady State.
