Description

The KTE7000 is a single-chip 5W wireless power receiver that conforms to WPC/Qi V-1.3 standards’ Baseline Power Profile (BPP) specifications. A wireless power receiver provides a 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 a low dropout voltage regulator (LDO) to efficiently convert the wireless AC power into 5V regulated DC output with up to 1.5A output current. An embedded MCU with OTP/ROM provides Qi-1.3 communication with the power transmitter, power management, and multi-protections.

The KTE7000 is packaged in an advanced, fully “green” compliant, 2.66mm x 3.90mm, 52-bump Wafer-Level Chip-Scale Package (6×9 WLCSP).
