IDT ( http://ko.idt.com/ , Country Manager Sang-Yup Lee), an analog-digital company providing core mixed-signal semiconductor solutions, announced a new ultra-compact wireless charging receiver that reduces board area by up to 70% compared to switching regulator-based solutions. Expanding IDT’s industry-leading wireless charging product line, this new product complies with Qi and PMA (Power Matters Alliance) standards and is suitable for cost-sensitive and high-density portable applications.

The IDTP9024, IDTP9025A, and IDTP9028 are highly integrated, single-chip wireless charging receivers that support PMA, WPC (Wireless Power Consortium) Qi 1.1, and dual-mode (PMA and Qi) standards, respectively. These products utilize a high-efficiency architecture based on low-dropout regulators (LDOs) to minimize component count, thereby significantly reducing board area and bill of materials (BOM). Furthermore, they improve wireless charging efficiency for devices by minimizing power loss through optimized control logic. Optimized for space and cost, these wireless charging receivers are suitable for wireless handsets, mobile phone cases, and tablets.

"Arman Naghavi, Vice President and General Manager of the Analog and Power Business Unit at IDT, said, 'We are pleased to expand IDT's industry-leading wireless charging portfolio with this new product optimized for ultra-compact portable applications.'" He explained, “Designed with IDT’s award-winning wireless charging platform, this new family of receivers provides customers with an upgrade path to the latest Qi and PMA standards based on fully proven technology.”

All three of IDT's newly released wireless charging receivers integrate high-efficiency synchronous full-bridge rectifiers, high-efficiency LDOs, and state-of-the-art control circuitry onto a single chip. These functions work in conjunction with a thin receiver coil to wirelessly receive power from a compatible transmitter and provide a regulated 5V output suitable for powering and charging mobile devices.

Using the IDTP9024 and IDTP9025A, you can develop portable devices that are fully compatible with transmitters compliant with any PMA or Qi standard. Designed to maximize usability, the IDTP9028 offers dual-mode performance, allowing for seamless conversion between Qi and PMA protocols and enabling power delivery compromises without requiring manual user intervention. Furthermore, its high integration density simplifies the system architecture, allowing designers to complete designs with minimal effort, and its adherence to verified standards ensures familiarity and ease of use.
