CIE Components in Electronics
Integrated Device Technology (IDT) has unveiled a new family of ultra-compact wireless power receivers offering a board area footprint reduction up to 70% compared to switching regulator-based solutions. The latest Qi- and PMA-compliant devices expand IDT’s industry-leading wireless power portfolio to address densely-populated, cost-sensitive portable applications.
The IDTP9024, IDTP9025A, and IDTP9028 are fully-integrated, single-chip wireless power receivers supporting PMA, WPC Qi 1.1, and dual mode (PMA and Qi) standards, respectively. The devices utilise a high-efficiency low-dropout regulator (LDO)-based architecture to reduce the component count, resulting in significant savings in board area and bill-of-materials (BOM) cost. In addition, optimised control logic minimises power losses to ensure highly-efficient power delivery to the load. These wireless power receivers are intended for wireless handsets, cell phone sleeves, and tablets.
According to Arman Naghavi, vice president and general manager of the Analog and Power Division at IDT, “Built on IDT’s award-winning wireless power platform, this new family of receivers offers customers an upgrade path to the latest Qi and PMA standards with the confidence afforded by a proven technology.”
All three wireless power receivers integrate a high-efficiency synchronous full bridge rectifier, high-efficiency LDO, and advanced control circuits in a single-chip. These functions work together with a thin receiver coil to wirelessly receive power from a compatible transmitter and provide a well-regulated 5 V output for powering and charging portable electronics.
The IDTP9024 and IDTP9025A enable the development of portable devices that are fully compatible with any PMA- or Qi-compliant transmitter, respectively. For maximum versatility, the IDTP9028 offers seamless dual-mode capability, switching between the Qi and PMA protocols and negotiating the power exchange without user intervention. The high-level of integration greatly simplifies the system architecture, enabling designers to complete their designs with minimal effort, while proven standards compliance ensures a user-friendly experience.
