IDT Expands Industry-leading Wireless Power Portfolio with Space-optimized Qi- and PMA-compliant Receivers to Address Densely-populated, Cost-sensitive Portable Applications
Integrated Device Technology, Inc. (IDT) announced 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 utilize a high-efficiency low-dropout regulator (LDO)-based architecture to minimize component count, resulting in significant savings in board area and bill-of-materials (BOM) cost. In addition, optimized control logic minimizes power losses to ensure highly-efficient power delivery to the load. The space- and cost-optimized wireless power receivers are ideal for wireless handsets, cell phone sleeves, and tablets.
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.
Pricing and Availability
The IDTP9024, IDTP9025A, and IDTP9028 are currently sampling to qualified customers, and are available in wafer-level CSP packages.
