DESCRIPTION

· The KTE7000 is a single-chip 5W wireless power receiver compliant with WPC/Qi V-1.3 standards, designed to convert wireless AC power into regulated 5V DC output with up to 1.5A current. It integrates a full-synchronous rectifier and a low dropout voltage regulator (LDO) for efficient power conversion. The device includes an embedded MCU with OTP/ROM for Qi-1.3 communication, power management, and multi-protection features. It is packaged in a 2.66mm x 3.90mm, 52-bump Wafer-Level Chip-Scale Package (WLCSP).
