What are the key features of TPS54140ADRCT?

Wide 3.5V to 42V input voltage range supporting industrial, automotive, and telecommunications power rails
1.5A output current with current-mode PWM control for fast transient response and inherent cycle-by-cycle current limiting
Compact 10-pin VSON package (JESD-30 code S-PDSO-N10) with lead-free e4 compliance for high-density board designs

What is TPS54140ADRCT used for?

The TPS54140ADRCT is designed for step-down DC-DC conversion in industrial automation equipment, telecom infrastructure, and automotive electronics where wide input voltage variation is common. Its current-mode control architecture delivers excellent load transient response and simplifies compensation design for fast-switching power supplies. The 42V maximum input makes it ideal for 24V and 36V industrial bus systems requiring efficient point-of-load regulation.

Frequently Asked Questions

What is the input voltage range and output current of the TPS54140ADRCT?

The TPS54140ADRCT accepts input voltages from 3.5V to 42V with a nominal 12V input, and delivers up to 1.5A of continuous output current, making it suitable for a wide range of industrial and automotive step-down conversion applications.

What control mode does the TPS54140ADRCT use and what are its benefits?

This device uses current-mode pulse width modulation (PWM) control, which provides inherent cycle-by-cycle current limiting for overcurrent protection, simplified frequency compensation, and fast transient response compared to voltage-mode control architectures.

What package does the TPS54140ADRCT use and is it RoHS compliant?

The TPS54140ADRCT is housed in a 10-pin VSON package with JESD-30 code S-PDSO-N10 and JESD-609 code e4, confirming it is lead-free and halogen-free, meeting RoHS and environmental compliance requirements for global markets.

What are typical applications for the TPS54140ADRCT?

Typical applications include point-of-load regulators for industrial 24V and 36V bus systems, automotive body electronics, telecom and networking equipment power rails, and any embedded system requiring efficient step-down conversion from a wide-range input to a lower regulated output voltage with up to 1.5A load current.
