RTKA223182DR0000BU
Dual Output 11W 3-phase Input Flyback Demonstration Board using RAA223182
The dual output 11W universal input Flyback
demonstration board, RTKA223182DR0000BU,
featured RAA223182 1000V regulator demonstrates
a low-cost, high-performance isolated AC/DC solution
from a universal 3-phase input of 121V
to 12.5V and 5V outputs for smart Meter applications.
The RTKA223182DR0000BU has proprietary
cost-saving features, such as the short-time heavy
load operation, which eliminates the need for
transformer over-design for the short-time heavy load
in communication. The board operates in DCM with
constant frequency at 50kHz in normal operation,
complimented with valley switching, reducing
switching losses and EMI noises. The board has built-
in protections against input brownout, V
OV, V UV, V OV, overload, output short-circuit,
IN IN
primary winding short, and over-temperature. The
board is pre-compliant with EN55022/CISPR 22
Class B conducted EMI limits and has the 4kV surge
capability by IEC61000-4-5 standard.
