TPS40000 - Synchronous Buck Controller

General Description

The TPS4000x are controllers for low-voltage, non-isolated synchronous buck regulators.

These controllers drive an N-channel MOSFET for the primary buck switch, and an N-channel MOSFET for the synchronous rectifier switch, thereby achieving very high-efficiency power conversion.

Key Features

  • D Operating Input Voltage 2.25 V to 5.5 V D Output Voltage as Low as 0.7 V D 1% Internal 0.7 V Reference D Predictive Gate Drivet N-Channel MOSFET Drivers for Higher Efficiency D Externally Adjustable Soft-Start and Overcurrent Limit D Source-Only Current or Source/Sink Current D Versions for Starting Into VOUT Pre-Bias D 10-Lead MSOP PowerPadt Package for Higher Performance D Thermal Shutdown D Internal Boostrap Diode D Fixed-Frequency, Voltage-Mode Control.
  • TPS40000/1/4 300-kHz.
