Design win for IDT, with wireless charging in LG’s G3 Smartphone

July 30, 2014 // By Graham Prophet
Integrated Device Technology(IDT) has secured a slot for its wireless power receiver in LG’s latest flagship G3 smartphone. The two companies worked together closely to integrate the IDTP9025A chip, which delivers a compact size and simplified application circuit.

Part of IDT's wireless power portfolio, the IDTP9025A is a fully integrated, single-chip wireless power receiver supporting the Wireless Power Consortium’s 1.1 standard. It uses a high-efficiency low-dropout regulator (LDO)-based architecture to minimise component count. Its optimised control logic minimises power losses to ensure efficient power delivery to the load. It is suited to wireless handsets, cell phone sleeves, and tablets.

“Enabling wireless charging by integrating the function into a device is key for long-term mass adoption,” said Ryan Sanderson, principal analyst for wireless power at IHS Technology. Sanderson added, “IHS predicts that in 2018, 600 million mobile phones will ship that will be enabled to charge wirelessly. Almost all of these are forecast to be enabled straight out of the box via integrated wireless power receivers.”

“To maintain a competitive edge, today’s technology leaders must squeeze more functionality into smaller and smaller form factors while keeping costs in check,” said Arman Naghavi, IDT’s vice president and general manager, Analog and Power Division. “Component size, integration, and quality are essential.”

IDT has expertise in both magnetic induction and magnetic resonance technologies for wireless charging, and actively participates in the Wireless Power Consortium (WPC), Power Matters Alliance (PMA), and Alliance for Wireless Power (A4WP) as a board member. IDT has introduced a true single-chip transmitter, the highest-output-power single chip receiver, and the first dual-mode receiver IC compatible with both WPC and PMA standards.
