Brief Description

The KTE7000 is a single-chip 5Watt wireless power

receiver that conforms to WPC/Qi standards v1.3

Baseline Power Profile (BPP) specifications. A wireless

power receiver provides regulated DC output power

derived from AC power that is magnetically coupled into

a connected wireless power receiver coil.

The KTE7000 integrates a full-synchronous rectifier and

an LDO to efficiently convert the wireless AC power into

5V DC output power at up to 1.5A. An embedded

microcontroller with ROM and OTP memory provides

power management, protection, and communications

with the power transmitter.

The KTE7000 is packaged in an advanced, fully “green”

compliant, 2.66mm x 3.90mm, 52-bump Wafer-Level

Chip-Scale Package (6x9 WLCSP).

Applications

• Mobile Internet Devices, IoT, Accessories

• Battery Powered Medical, Industrial, Consumer

• Wireless Headsets, Headphones, Earbuds
