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.
