TPS40003 - Synchronous Buck Controller

Download the TPS40003 datasheet PDF. This datasheet also covers the TPS40000 variant, as both devices belong to the same synchronous buck controller family and are provided as variant models within a single manufacturer datasheet.

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.

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.
