Renesas RTKA223012DR0050BU Manual

RTKA223012DR0050BU, RTKA223012DR0060BU
The RAA223012 demonstration boards
(RTKA223012DR0050BU and
RTKA223012DR0060BU) are high voltage buck or
buck/boost converters that demonstrate low-cost high
performance non-isolated AC/DC conversion from a
universal input of 85V
AC
a -5V with the output current up to 150mA.
The board can be configured to a Buck or a
Buck/Boost converter by using jumper (JP1) without
changing the output polarity. It has built-in
overcurrent, short-circuit, input brownout, and
over-temperature protection, and is designed on a
compact PCB with a low-cost half-wave input
rectification. It is pre-compliant with conducted and
radiated EMI requirements by EN55022/CISPR22
and the 1.5kV surge test by IEC61000-4-5 standard.
RTKA223012DR0050BU comes with a RAA223012
in a SO8 package. RTKA223012DR0060BU comes
with a RAA223012 in aSOT23-5 package.
