Applications
The TPS54335ADRCT is well-suited for industrial equipment, communications infrastructure, and embedded computing boards that require a compact, high-efficiency DC-DC converter from a 12 V or 24 V bus to lower-voltage processor or peripheral rails. Its 0.8 V minimum output makes it compatible with modern FPGAs and DSPs that demand sub-1 V core voltages, while the 28 V maximum input accommodates automotive-adjacent and wide-input applications.

Frequently Asked Questions
What is the input voltage range and maximum output current of the TPS54335ADRCT?
The TPS54335ADRCT accepts an input voltage from 4.5 V to 28 V and delivers up to 3 A of continuous output current. The output voltage is adjustable from 0.8 V to 24 V using an external resistor divider, making it suitable for powering a wide range of digital and analog loads from a single 12 V or 24 V supply rail.
Which industrial or embedded designs are a good fit for the TPS54335ADRCT synchronous buck converter?
Industrial PLCs, 24 V panel PCs, FPGA development boards, and telecom line cards benefit most from this converter. Its 4.5 V–28 V input range accommodates standard 12 V and 24 V distribution buses, while the 3 A current rating and 0.8 V minimum output cover core rails for modern processors and FPGAs. Current-mode PWM control ensures fast transient recovery when loads change rapidly.
How does the TPS54335ADRCT compare to a non-synchronous buck when efficiency at light loads matters?
The synchronous topology of the TPS54335ADRCT replaces the external catch diode with an integrated low-side MOSFET, reducing conduction losses by roughly 0.3 V to 0.6 V compared to a Schottky diode drop. At medium loads around 1 A to 2 A from a 12 V input, this can improve conversion efficiency by 3% to 5%, reducing heat dissipation and extending battery life in portable or fanless industrial enclosures.
What package does TPS54335ADRCT use, and how compact is the recommended PCB footprint?
TPS54335ADRCT is housed in a 10-pin MSOP (S-PDSO-N10) package measuring approximately 3 mm × 3 mm. The small footprint, combined with integrated MOSFETs, means the complete power stage — including inductor and capacitors — typically fits within 1 cm² of PCB area at switching frequencies up to 570 kHz, which also reduces the required inductance to around 3.3 µH to 10 µH.
