TPS543A26 - Step-Down Converter

General Description

The TPS543A26 is a high-efficiency 18V, 16A synchronous buck converter employing an internally compensated, fixed-frequency advanced current mode (ACM) control architecture, which while always operating under FCCM, generates output voltages from 0.5V to 7V.

Key Features

  • Fixed-frequency, internally compensated, advanced current mode (ACM) control.
  • Integrated 6.5mΩ and 2mΩ MOSFETs.
  • 4V to 18V input voltage range.
  • 0.5V to 7V output voltage range.
  • True differential remote sense amplifier (RSA).
  • Three selectable PWM ramp options to optimize the control loop performance.
  • Five selectable switching frequencies: 500kHz, 750kHz, 1MHz, 1.5MHz, and 2.2MHz.
  • Synchronizable to an external clock.
