TPS40303 - Synchronous Buck Controller

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.
