What are the key features of TPS54227DRCT?
- Integrated synchronous rectification with 2 A continuous output current eliminates external catch diode
- Wide 4.5 V to 18 V input voltage range suits 5 V, 9 V, 12 V, and 15 V industrial rails
- Adjustable output down to 0.76 V supports low-voltage core rails in FPGAs and DSPs
What is TPS54227DRCT used for?
The TPS54227DRCT is well-suited for point-of-load power conversion in industrial automation, communications infrastructure, and test-and-measurement equipment operating from 12 V system buses. Its adjustable output range makes it ideal for generating precisely regulated 1.0 V, 1.2 V, 1.8 V, or 3.3 V rails for microcontrollers, FPGAs, and DDR memory. The compact SON-10 footprint and integrated switches simplify PCB layout in space-constrained designs such as embedded computing modules and wireless access points.

Frequently Asked Questions
What input and output voltage ranges does the TPS54227DRCT support?
The TPS54227DRCT accepts a wide input voltage range of 4.5 V to 18 V, making it compatible with 5 V, 9 V, 12 V, and 15 V supply rails common in industrial and communications systems. The adjustable output can be set anywhere from 0.76 V to 7 V, enabling regulation of core voltages like 1.0 V, 1.8 V, and 3.3 V with a single device.
How does the TPS54227DRCT achieve high efficiency at 2 A continuous output?
The TPS54227DRCT integrates high-side and low-side MOSFETs for synchronous rectification, eliminating the power loss of an external catch diode and enabling efficiencies above 90% at 2 A full load. Voltage-mode PWM control with adjustable frequency lets designers optimize switching losses versus inductor size for specific 2 A load conditions.
Which PCB footprint and thermal characteristics apply to the TPS54227DRCT SON-10 package?
The TPS54227DRCT ships in a 3 mm x 3 mm SON-10 package with an exposed thermal pad that provides low junction-to-board thermal resistance, typically around 30 °C/W, supporting continuous 2 A output without excessive heating. The compact 10-pin footprint reduces board area versus DFN or SO-8 alternatives in tight power supply layouts.
Can the TPS54227DRCT replace the TPS54228 or TPS54229 in existing designs?
The TPS54227DRCT shares the same 4.5 V to 18 V input range and 2 A rating as the TPS54228 and TPS54229 family members but differs in soft-start, enable, and frequency-adjust pin assignments, so pin-for-pin compatibility must be verified against your schematic before substitution. Checking the TPS5422x datasheet for the specific DRCT variant confirms whether compensation components and inductor values carry over unchanged.
What switching frequency range does the TPS54227DRCT operate at, and how does it affect component selection?
The TPS54227DRCT supports a programmable switching frequency from approximately 100 kHz to 2.5 MHz set by an external resistor on the RT pin. Higher frequencies, such as 800 kHz or 1 MHz, allow smaller inductors in the 1 µH to 4.7 µH range but increase switching losses, while lower frequencies around 200 kHz to 400 kHz use larger inductors of 10 µH to 22 µH with lower gate-drive power dissipation.
