GaN enables compact 160W AC-DC adapter
TRUMPower has used gallium nitride GaN FETs for a 160W AC-DC adapter with higher conversion efficiency for industrial and ITE applications.
The TTG160 AC-DC adapter series has an average efficiency of 91 to 93 percent with a no-load power consumption of 210mW. The 160W adapter meets the latest global energy efficiency standards for external supplies with its compliance to DoE Level VI.
The TTG160 series comes in a compact 6.34” (L) x 2.13” (W) x 1.31” (H) enclosure for Class I models and 5.91” (L) x 2.13” (W) x 1.30” (H) enclosure for Class II models. This gives the series a power density of 10W/in3. The AC-DC adapter has a wide range of AC inlet options which include IEC 320/C6 and IEC 320/C14 for class I models or IEC 320/C8 for class II requirements.
There are five standard single output voltages of 12, 19, 24, 48, and 56 VDC and the series offers thermal shutdown to help protect the AC-Dc adapter from over-temperature conditions. The series operates with a universal input range of 100 to 240 VAC and operating temperatures between 0°C to +70°C ambient, while derating linearly from 100 percent load at +40°C to 50 percent load at +70°C (for 19V to 56V models) and from 100 percent load at +40°C to 50 percent load at +60°C (for the 12V model).
The units are reliable with 300,000 hours minimum MTBF at 25°C ambient, calculated per Telcordia SR-332.
The TTG160 series carries the CE marking, is RoHS compliant, and is approved by UL/cUL, PSE and TUV to the latest ITE standards, including IEC/EN/UL 62368-1:2014, CAN/CSA 22.2 No. 62368-1-14 and IEC/EN/UL 60950-1 2nd edition. The power adapter complies with EMC and immunity standards including EN 55032, CISPR 32/FCC,VCCI class B (conducted and radiated emissions), EN 61000-3-2, EN 61000-3-3, EN 61000-4-2, EN 61000-4-3, EN 61000-4-4, EN 61000-4-5, EN 61000-4-6, EN 61000-4-8, EN 61000-4-11. It also meets energy star 2.0, ErP stage 2, CoC tier 2, NRCan & GEMS level VI standards.
The TTG160 is competitively priced in OEM quantities.
