Frequently Asked Questions
What is the input voltage range of the TPS54240DGQR?
The TPS54240DGQR operates over a wide input voltage range of 4.5V to 42V, making it suitable for 12V, 24V, and 36V bus systems commonly found in industrial and automotive applications.
How much output current can the TPS54240DGQR deliver?
The TPS54240DGQR can deliver up to 2.5A of continuous output current. It integrates a high-side MOSFET and requires an external low-side diode, allowing designers to optimize efficiency and thermal performance for their specific load requirements.
What switching frequency does the TPS54240DGQR use?
The TPS54240DGQR uses a fixed 500kHz switching frequency. This relatively high frequency reduces the size of the external inductor and output capacitors, helping achieve a compact PCB footprint in space-constrained designs.
What package is the TPS54240DGQR available in?
The TPS54240DGQR is available in a 10-pin MSOP-PowerPAD (DGQR) package, which provides an exposed thermal pad for improved heat dissipation, enabling the device to deliver full 2.5A output current in typical PCB environments.
What are typical applications for the TPS54240DGQR?
Typical applications include industrial 24V rail step-down converters, factory automation equipment, telecom power supplies, motor drive pre-regulators, and any system requiring an efficient wide-input buck converter with up to 42V input tolerance.
