BP5220 / BP5221 / BP5222 / BP5220X / BP5221X / BP5222X The BP5220, BP5221, BP5222, BP5220X, BP5221X, and BP5222X are DC / DC con
v
e
r
ters that use a pulse
width modulation (PWM) system.

The
y contain control circuits
, s
witching de
vices
, rectifiers
, and coils
, and oper
ate
b
y
only connecting an I / O smoothing capacitor
.

With a high efficiency of po
w
er con
v
ersion, the modules are
a
v
