Key Features
- Wide 4.5 V to 18 V input range with adjustable output from 0.76 V to 7 V covering a broad range of point-of-load rails
- 2 A continuous output current with integrated high-side and low-side MOSFETs for high efficiency and small external component count
- Voltage-mode PWM at 570 kHz reduces inductor and capacitor size while enabling fast transient response in tight PCB layouts
Applications
TPS54227DDAR is used in industrial control boards, telecom line cards, and distributed power architectures where a 12 V bus must be stepped down to 1.8 V, 3.3 V, or 5 V rails at up to 2 A. Its wide input range also suits 24 V automotive accessory and factory automation power supplies. The compact HSOP-8 package and internal MOSFETs simplify PCB layout and reduce component count.

Frequently Asked Questions
What output voltage range can TPS54227DDAR achieve and how is it set?
TPS54227DDAR supports an adjustable output voltage from 0.76 V to 7 V, programmed with an external resistor divider connected to the FB pin. The 0.76 V reference allows generation of sub-1 V core rails for FPGAs and DSPs, while the 7 V ceiling covers 5 V and higher logic supplies from a 12 V or 18 V input bus.
How does TPS54227DDAR perform in a 12 V to 3.3 V, 2 A industrial power supply application?
Operating from a 12 V input at 570 kHz switching frequency, TPS54227DDAR delivers a regulated 3.3 V output at up to 2 A with typical efficiency above 90%. The synchronous rectification eliminates the external catch diode, and the internal 4.5 mΩ high-side and 3.5 mΩ low-side MOSFETs keep conduction losses low in industrial and telecom applications.
When is TPS54227DDAR a compact alternative to a discrete switching regulator design using a TPS5430?
TPS54227DDAR integrates both power switches and the gate driver in an 8-pin HSOP, so it replaces a TPS5430 plus an external Schottky diode and gate resistors, saving roughly 30% board space. Its 2 A synchronous topology also improves efficiency at light loads, making it preferable when thermal budget below 85°C is critical.
