Datasheet

TPS54040DGQR – 0.5A, 42V SWIFT Step-Down Switching Regulator IC

The TPS54040DGQR is a high-performance 0.5A, 3.5V–42V step-down (buck) converter from Texas Instruments’ SWIFT family, designed for high-efficiency power conversion in industrial, automotive, and communication systems. Featuring an integrated 200mΩ high-side MOSFET, this regulator provides robust performance with minimal external components, making it ideal for compact and reliable DC-DC power designs. With a low ripple pulse-skip Eco-mode, the converter maintains high efficiency even at light loads, drawing just 116uA quiescent current, and only 1.3uA in shutdown mode when the enable pin is pulled low. Additional features such as slow start/sequencing, Power Good indication, adjustable UVLO, and comprehensive protection circuitry (frequency foldback, cycle-by-cycle current limit, and thermal shutdown) ensure safe and reliable operation. The thermally enhanced 10-pin HVSSOP PowerPAD package delivers superior heat dissipation and compact form factor for high-density PCB layouts.

Key Features

  • Wide Input Voltage Range: 3.5V to 42V for industrial and automotive applications.
  • Integrated 200mΩ MOSFET: Delivers efficient 0.5A continuous output current.
  • Adjustable Switching Frequency: 100kHz to 2.5MHz, with external synchronization support.
  • Eco-mode Operation: Reduces no-load current to 116µA for improved light-load efficiency.
  • Low Shutdown Current: 1.3uA typical when disabled via EN pin.
  • Slow Start and Sequencing: Adjustable via dedicated SS pin for controlled power-up and tracking.
  • Power Good Indicator: Open-drain output signals when voltage is within 93%–107% of nominal.
  • Adjustable UVLO: Settable with precision enable pin for flexible undervoltage protection.
  • Comprehensive Protection: Includes frequency foldback, current limiting, and thermal shutdown.
  • Compact HVSSOP-10 PowerPAD Package: Provides excellent thermal performance and compact size.
