75 Watt, Single-Output Benchtop Power Supply

Overview

TopologyBuck Converter
Input voltage42 V
Output 11.7 V / 6 A

Description

The CN-0508 provides a low cost, adjustable power solution with performance comparable to high-performance commercial power supplies. The design uses a hybrid circuit topology of a buck converter preregulator and two parallel linear regulators. This topology combines the high power efficiency of a buck converter and the low output noise, low ripple, and adjustable current limiting of the linear regulators. No heat sink other than the circuit board itself is required, in contrast to linear bench supplies in which pass devices (either discrete transistors or integrated circuit regulators) require external heat sinks to sufficiently dissipate the heat.
