REF_XDPS2221_140W1

Überblick

140 W reference board for ultra-high power density in USB-C chargers with EPR and adapters

The reference board REF_XDPS2221_140W1 was developed for USB-PD applications with a wide input range and output voltage from 5 V to 28 V. The nominal output power of this design is 140 W.

It features the industry’s first PFC + hybrid flyback combo controller XDP™ digital power XDPS2221, CoolGaN™ 600 V GIT HEMTs (IGLD60R190D1) as the main switch, and on the secondary side the BSC040N10NS5 OptiMOS™ 5 N-channel MOSFET serving as the SR switch. The P-channel HEXFET™ power MOSFET IRF7240 is the safety switch and the EZ-PD™ CCG3PA was implemented for PD control.

The board has a dimension of 109.5 mm x 38.5 mm x 24 mm and a power density of 22.67 W/in³. Two layers PCBs are used for the whole system, which results in low system cost. The board fulfills the efficiency requirement from DOE VI and CoC Tier 2. The 5 V standby input power is below 75 mW.
