36 VDC to 75 VDC Input, 50-150W Output
Introduction
The AV60C half-brick series of switching DC-
DC converters is one of the most cost effective
options available in component power. The
AV60C series uses an industry standard pack-
age size of
2.4” x 2.28” x 0.5”
and pinout con-
figuration, provides standard control, trim, and
sense functions, also features high power den-
sity up to
54.8W/in
3
which gives more selectiv-
ity to meet small size requirement.
AV60C half-brick series comes in 48V input ver-
sion with a 2:1 ( 36-75V ) input range. This
series has input LVP, output OVP, OCP, short
circuit protection and over temperature protec-
tion. There are isolated single output 3.3V, 5V,
12V, 15V and the isolation voltage is 1500Vdc.
This series is designed to meet CISPR22, FCC
class A, UL and CSA certifications.
The design features of the AV60C half-brick
series set a new standard for high density
power converters. The unit employs an alu-
minum baseplate to carry all of the power com-
ponents, and conduct the dissipated heat to the
ambient. A conventional, multi-layer printed cir-
cuit board, over the top of the power substrate,
contains all of the small signal control circuitry,
all constructed with automated SMD technolo-
gy.
