Description

The KTE7001 is a single chip, 15W wireless power receiver that conforms to WPC/Qi V-1.3 Extended Power Profile (EPP) standard 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 KTE7001 integrates a full synchronous rectifier and LDO to efficiently convert the wireless AC power into up to 12V DC regulated power at up to 1.5A. The embedded microcontroller with firmware and OTP/ROM memory provides system monitoring, protection, and communications back to the power transmitter.

The KTE7001 is packaged in an advanced, fully “green” compliant, 2.66mm x 3.90mm, 52-bump Wafer-Level Chip-Scale Package (6×9 WLCSP)
