In a ceremony on 28 May, after a rigorous selection process including online voting, Fairchild’s FAN54015 USB-compliant single-cell Li-ion switching charger was announced as the winner of Electronic Engineering & Product World (EEPW) 2013 Power Supply Technology and Product Award in the Best Application Award for Charging (Battery Management).

Fairchild FAN54015 USB-compliant single-cell Li-ion switching charger provides designers a balance of safety, accuracy, efficiency, and solution size for charging mobile device batteries.

The device employs a high-efficiency, eco-friendly, 3 MHz DC-DC synchronous buck converter capable of supplying 1.45 A. Additionally, to accommodate legacy and emerging lithium battery technologies, the regulated battery float voltage can be programmed from 3.5 V to 4.44 V. The FAN54015’s innovative system architecture allows reverse use of the switch-mode buck converter, resulting in a 500 mA USB on-the-go (OTG) boost regulator, and providing power for USB peripherals.

To protect the battery and maximize mobile device usage time, the FAN54015 device supports battery charging in three phases: pre-conditioning, constant current (CC), and constant voltage (CV). An integrated over-voltage protection (OVP) FET blocks current flow when the input voltage reaches dangerous levels, eliminating the need for an external protection MOSFET and thereby reducing complexity and bill of material (BOM) costs.

This year’s EEPW award considered over 60 power supply technologies and products from 22 companies. More than 1000 netizens participated in the online voting. The final result reflected the widespread support of netizens for power supply technologies and products.

“We are honored to receive this award, as it validates our customer-centric focus and our passion solving real-world problems – like mobile charging – and recognizes Fairchild’s power technology and application support for the China mobile market , Richard Lu, Fairchild’s Vice President of Mobile Solutions, said. “Fairchild remains committed to delivering amazing semiconductor solutions that help our customers address short design cycles, the demand for increased functionality, the need for decreased power consumption and other challenges.”
