TPS40305 - Synchronous Buck Controller

Download the TPS40305 datasheet PDF. This datasheet also covers the TPS40303 variant, as both devices belong to the same synchronous buck controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The TPS4030x is a family of cost-optimized synchronous buck controllers that operate from 3-V to 20-V input.

The controller implements a voltage-mode control architecture with input-voltage feed-forward compensation that responds instantly to a change in input voltage.

Key Features

  • 1 Input Voltage Range From 3 V to 20 V.
  • 300-kHz (TPS40303), 600-kHz (TPS40304), and 1.2-MHz (TPS40305) Switching Frequencies.
  • High- and Low-Side FET RDS(on) Current Sensing.
  • Programmable Thermally Compensated OCP Levels.
  • Programmable Soft Start.
  • 600-mV, 1% Reference Voltage.
  • Voltage Feed-Forward Compensation.
  • Supports Prebiased Output.
  • Frequency Spread Spectrum.
  • Thermal Shutdown Protection at 145°C.
