What are the key features of TPS566247DRLR?
- FCCM operation maintains low output ripple at light loads, eliminating audible noise in noise-sensitive RF and audio applications
- 6 A continuous output current in a SOT-563 footprint achieves >400 mA/mm² current density for ultra-compact power stages
- 3 V to 16 V wide input range covers 5 V USB, 12 V server, and 15 V notebook adapter rails in a single design
What is TPS566247DRLR used for?
The TPS566247DRLR is used in FPGA core and I/O power rails, point-of-load converters for SSDs and network switches, and RF module power supplies where FCCM mode eliminates variable switching frequency noise that would otherwise desensitize RF receivers. Its 6 A output in a 1.6 mm × 1.6 mm SOT-563 package suits space-constrained server blade and M.2 storage designs. Notebook computers and gaming hardware use it to power DDR5 VDDQ rails from the 12 V main bus.

Frequently Asked Questions
Why should a designer choose FCCM mode on the TPS566247DRLR for an RF system-on-module power supply?
FCCM mode in the TPS566247DRLR maintains a constant switching frequency—typically 2 MHz to 4 MHz—across all load conditions from 0 A to 6 A, preventing the variable-frequency switching noise that diode emulation mode generates. In an RF SoM with a 2.4 GHz receiver, a switching frequency hop from 200 kHz to 1 MHz at light load would land harmonics directly in the receiver band, raising the noise floor by 10 dBm to 20 dBm. FCCM keeps harmonics predictable and filterable with a fixed LC network.
For a compact M.2 2280 SSD design, how does the TPS566247DRLR SOT-563 package compare to a WSON-8 alternative in terms of board area?
The SOT-563 package of the TPS566247DRLR measures 1.6 mm × 1.6 mm with 6 leads on a 0.65 mm pitch, occupying approximately 2.56 mm² of PCB area including pads. A WSON-8 package for a comparable 6 A converter measures 2 mm × 2 mm, using about 4 mm² — over 50% more area. On an M.2 2280 SSD where the power supply must fit within a 5 mm × 10 mm corner zone, this difference allows placement of two decoupling capacitors in the space saved.
What output voltage range can the TPS566247DRLR regulate from a 12 V input rail and what sets the minimum achievable output?
From a 12 V input, the TPS566247DRLR can regulate output voltages from 0.6 V to approximately 10 V, with the minimum set by the 0.6 V internal reference and two external resistors forming the feedback divider. The minimum duty cycle of approximately 5% at 2 MHz switching frequency sets a practical lower limit of about 0.6 V, while the maximum is limited by the 16 V input rating and 90% maximum duty cycle, giving an upper bound of roughly 14 V on a 16 V input.
