High-efficiency wireless power transmitters for wire-free charging
As an expansion to IDT’s existing portfolio of products, these compact transmitters feature low electromagnetic interference (EMI) and high efficiency; the P9235 and P9236 transmitters are compliant with the latest Wireless Power Consortium (WPC) Qi standard, while the P9234 is a Power Matters Alliance (PMA)-compliant device.
IDT is also introducing a proprietary-mode device, the P9231, which operates at resonant frequency of up to 1 MHz, allowing for a smaller coil. To complete the product offering, IDT’s P9230 is a dual-mode transmitter, supporting both WPC and PMA standards. Collectively, the P923x family addresses all of the various WPC low-power coil configurations, the company says.
Incoportating an integrated 32-bit ARM Cortex-M0 processor, the P923x family offers a high level of programmability and flexibility while consuming very low standby power to meet Energy Star requirements. The transmitters span input voltages ranging from 4.0 V to 21 V and target applications requiring from 0.5 to 10W of power. The devices integrate all digital and analogue functions.
The P9235 is a full-bridge, single coil device, compliant with WPC A5/A11, QFN5X5-40, while the P9236 is a half-bridge, single and multi-coil configuration, QFN6X6-48.
Available soon are the P9230, a half-bridge dual-mode chip compliant with WPC A1/A10 and PMA type 3 configurations, the P9231, designed for proprietary mode applications, including wearables, and the P9234, a PMA-compliant transmitter.
