Linear eliminator delivers 5W

Paul Boughton

Phihong USA has developed a cost-effective 5W linear adapter. The PSAA05A adapter provides high efficiency in a small package size, making it suitable for applications such as MPEG players, PDAs and digital cameras.

“The adapter is CEC and Energy Star compliant,” said Keith Hopwood, vice president of marketing for Phihong USA. “Housed in a small footprint and providing 5W of power, it is a low-cost solution for many personal electronics OEMs.”

Measuring just 2.59 x 1.55 x 1.07 inches and weighing 3.0 ounces, the adapter features double insulation and class B EMI. The adapter is equipped with an auto restart for short circuit protection, and the output can be shorted permanently without damage. It also features a dc output connector of a mini USB.

The 5W adapter features a no-load power consumption of less than 0.3W at 230Vac, and a low leakage current of 20ºA. Ac input voltage is 100Vac to 240Vac with a maximum ac input current of 0.3A at 90Vac. Dc output voltage is 5.15V and the device has maximum over-voltage protection of 6.7Vdc (±0.5).

The PSAA05A adapter is approved and listed by cUL/UL, TUV, CE, SAA, and C-TICK for 60950-1 safety approvals.
