TPS40041 - SYNCHRONOUS BUCK DC-TO-DC CONTROLLER

Download the TPS40041 datasheet PDF. This datasheet also covers the TPS40040 variant, as both devices belong to the same synchronous buck dc-to-dc controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The TPS40040 and TPS40041 dc-to-dc controllers are designed to operate from a 2.25-V to 5.5-V input source.

To reduce the number of external components, several operating parameters are fixed internally; namely, frequency, soft start time, and short circuit protection (SCP) levels.

Key Features

  • 1.
  • 23 2.25-V to 5.5-V Input.
  • Output Voltage from 0.6 V to 90% of VIN.
  • High-Side Drive for N-Channel FET.
  • Supports Pre-Biased Outputs.
  • Adaptive Anti-Cross Conduction Gate Drive.
  • 1%, 0.6-V Reference.
  • Two Fixed Switching Frequency Versions, TPS40040 (300 kHz) and TPS40041 (600 kHz).
  • Three Selectable Short Circuit Protection Levels of 105 mV, 180 mV and 310 mV.
  • Hiccup Restart from Faults.
  • Voltage Mode Control.
