Key Features
- 4.5 V to 28 V wide input range covers 5 V, 12 V, and 24 V industrial supply rails
- 3 A continuous output current with Eco-mode reduces quiescent power at light loads
- Adjustable output voltage from 0.8 V to 24 V supports diverse core and I/O rail requirements
- Current-mode PWM control provides fast transient response and loop stability over load range
Applications
The TPS54335-2ADRCT is used in industrial automation and factory equipment powered from 12 V or 24 V rails, where its 4.5 V to 28 V input range and 3 A output supply FPGAs, microcontrollers, and sensor nodes. Telecom and networking boards running from 12 V bus voltages rely on its synchronous topology and Eco-mode to maintain high efficiency from light to full 3 A loads. Battery-powered portable instruments and point-of-load converters on server cards also benefit from its adjustable 0.8 V to 24 V output and compact footprint.

Frequently Asked Questions
How wide is the input voltage range of TPS54335-2ADRCT and which supply rails does it support?
The TPS54335-2ADRCT accepts input voltages from 4.5 V to 28 V, covering standard 5 V, 12 V, and 24 V industrial and telecom supply rails. This wide range allows a single design to work across multiple system voltage buses without redesigning the power stage or changing the inductor and capacitor values.
What output current can TPS54335-2ADRCT deliver and how does Eco-mode improve light-load efficiency?
The TPS54335-2ADRCT delivers up to 3 A continuous output current. Its Eco-mode reduces switching frequency at light loads (below roughly 50 mA) by entering a pulse-skipping mode, cutting switching losses and improving efficiency by several percentage points at 5% to 20% load conditions compared to fixed-frequency operation.
To what output voltage range can the TPS54335-2ADRCT be adjusted and what sets the output voltage?
Output voltage is adjustable from 0.8 V to 24 V using 2 external resistors forming a voltage divider from the output to the feedback pin. The 0.8 V reference allows generation of low-voltage rails for FPGA cores, DDR termination, and ARM processor I/O supplies while the 24 V upper limit enables high-output-voltage regulation from the 28 V input.
How does TPS54335-2ADRCT's current-mode control improve transient response in dynamic load applications?
Current-mode PWM control in the TPS54335-2ADRCT samples inductor current every switching cycle, allowing the control loop to correct load transients within 1 to 2 switching cycles. This fast inner current loop reduces output voltage deviation during sudden load steps from 0.5 A to 3 A, which is critical for FPGAs and DSPs with unpredictable core current demand.
