Phihong USA Selects Power Integrations' LinkSwitch ICs

“Using PI’s LinkSwitch-LP has enabled us to design our PLA family of adapters with a the small footprint, no-load consumption of less than 0.3W at 230VAC and a low leakage current of 250uA. We plan to use PI ICs in the design of our 1-, 2- and 3W PLA family of linear replacement adapters,” said Michael Mueller, vice-president of sales, Phihong USA.

“Energy-efficiency standards practically eliminate the use of linear-regulated external power supplies in key markets such as California, making it necessary for OEM suppliers to move to new power supply solutions in the immediate future,” noted Doug Bailey, vice president of marketing, Power Integrations. “Phihong has addressed the needs of the OEMs with its new PLA family of adapters. These new adapters are CEC and ENERGY STAR compliant and offer OEMs a low-cost power supply solution for personal electronics.”

Phihong PLA external charger/adapters provide single outputs from 3 V to 12 V, and outputs ranging from 1 to 3W in a significantly smaller package size than many linear power supplies. In addition, each model meets all voluntary and mandatory environmental regulations for no-load current drain and efficiency. The PLA series are priced from $3.38 for most 1-watt models to $3.98 for 3W models in quantities of 1000. They are available in sample quantities from Phihong distributors.
