Introduction

The AV45C quarter-brick series comes in a

industry standard quarter-brick package of

1.45" x 2.28" x 0.5" and footprint, and incorpo-

rates

the

super

high

efficiency

90%(@5Vout), and high power density up to

60.5W/in3. The input range is 36V-75V, and

input is fully isolated from output and the isola-

tion voltage is 1500Vdc.

The typical efficiencies are 90% for the 5V

output, 89% for the 3.3V output, 85% for the

1.8V and 1.5V output.

Designed using a synchronous rectification

topology, AV45C series incorporates simple

structure, good electrical performance and high

reliability. Standard features include input LVP,

output OVP, OCP, short circuit protection, and

over-temperature protection.

The AV45C quarter-brick series is designed to

meet CISPR22, FCC Class A, UL, TUV, and

CSA certifications.
