描述
The P9027LP-R is a highly integrated, low BOM count, single-chip receiver targeted for applications up to 3W. The receiver is designed to convert an AC power signal from a resonant tank into a programmable, regulated voltage ranging from 4.5 to 6.0 V. The device includes a high-efficiency synchronous full-bridge rectifier, a fast-tracking, NMOS LDO, and a charge pump to improve startup under very weak coupling or poor alignment conditions.
The P9027LP-R includes a patented internal scheme for modulation and communication using no additional external components. As a result, it provides an extremely small application area. The P9027LP-R is available in a WLCSP-40 package (2.24 x 3.62 mm), and it is rated for 0 to +85°C temperature range.
The P9027LP-R with the P9235A-R transmitter make a complete solution for <3W power applications.
