Description

The P9027LP-R is a highly integrated, low Bill-of-Materials (BOM)

count, single-chip receiver targeted for 0.5 to 3 W applications.

Using the magnetic inductive charging technology, it converts an

AC power signal from a resonant tank into a regulated

programmable DC output voltage ranging from 4.5 to 6.0 Volts.

The receiver has a patented internal scheme for communication

and modulation using zero external components. As a result, it

provides an extremely small application area. Together with the

P9235A-R transmitter, the P9027LP-R is a complete wireless

power system solution.

The P9027LP-R is available in a WLCSP-40 package (2.24 mm ×

3.62 mm, 0.4 mm pitch), and it is rated for 0 to 85°C ambient

operating temperature range.
