The isolated DC-DC converter evaluation board provides power supply designers with a highly efficient 100 W reference design in a quarter-brick form factor.
New isolated DC-DC converter development tools increase power density of modular and embedded power supplies
Santa Clara, CA and Austin, TX–National Semiconductor Corp. (NYSE:NSM) and Silicon Laboratories Inc. (Nasdaq:SLAB) have announced a new quarter-brick isolated DC-DC converter evaluation board and reference design to help power supply designers get higher power density in networking, communications and high-end server applications.
Featuring National Semiconductor’s LM5035C pulse-width modulation (PWM) controller and Silicon Labs’ Si8420 ISOpro digital isolator, the isolated DC-DC converter evaluation board provides power supply designers with a highly efficient 100 W reference design in a quarter-brick form factor.
The evaluation board reduces the time required for product characterization and design adaptation to the customer’s specific requirements.

“National’s LM5035C half-bridge PWM controller enables industry leading power density and performance advantages for small form factor DC-DC converters by integrating the bias regulator, gate drivers and synchronous rectifier controls into a single IC,” says Jim MacDonald, marketing director for National Semiconductor’s Infrastructure Power business unit.
“The reference design with Silicon Labs enables even further power density improvements by combining industry-leading power control and isolation technology.”
The reference design demonstrates a viable 36V to 75V input half-bridge converter for power module or embedded power applications. The design survives input transients up to 100V as commonly required in communications equipment and protects the power distribution system with hiccup-mode fault protection.
“Silicon Labs’ patented ISOpro digital isolation products provide significant performance advantages including lower power, industry-leading EMI performance and world-class reliability using standard CMOS process technology,” says Mark Thompson, vice president and general manager of Silicon Labs’ Embedded Mixed Signal products.
“The reference design with National Semiconductor validates our industry-leading digital isolation technology and puts our customers on the fast track to developing power modules for their embedded applications.”
