Small and low cost USB charger from Phihong

Phihong has developed the small and low-cost 2.75W USB charger. Measuring 42 x 43 x 21mm with a weight of 80 grams, the PSM03E is compliant with the new ENERGY STAR EPS version 2.0 as well as the European Union's Ecodesign Directive 2009/125/EC for Energy-related-Products level 2 Annex 1b, and the 5-Star Standby Power standard. The small size of the charger makes it ideal for wireless communications, peripherals, networking, portable and mobile equipment applications such as MP3 players, PDAs, digital cameras and mobile phones, the PSM03E provides a fully regulated 5VDC output and a maximum no-load power consumption of <0.03 watts. The device is IEEE1725-certified for charging batteries in mobile phones. The USB mobile charger has a constant-current/constant-voltage feature to charge lithium ion batteries quickly.

"Energy efficiency standards are increasingly important for all electronic equipment, especially for personal and mobile devices for which USB chargers are standard accessories," said Keith Hopwood, vice president of marketing for Phihong USA. "Achieving compliance with energy efficiency standards is of vital importance in our design of new products, and the PSM03E adapter is a direct response to the mobile phone industry's directive in the 5-Star Standby Power standard."


The standard mobile charger also includes a low-profile case that is halogen-free and therefore will not give off toxic smoke in the event of a fire. The charger contains short-circuit protection, over-current protection and over-voltage protection. The functional operating temperature is between 0°C to 45°C. The adapter also meets RoHS, REACH and WEEE directives and is marked for CE compliance.
