National Semiconductor and Silicon Laboratories have announced a new quarter-brick isolated DC-DC converter evaluation board and reference design to help power supply designers achieve higher power density.
Featuring National’s LM5035C pulse-width modulation (PWM) controller and Silicon Labs’ Si8420 ISOpro digital isolator, the evaluation board provides a highly efficient 100 W reference design in a quarter-brick form factor. It demonstrates a viable 36 V to 75 V input half-bridge converter for power module or embedded power applications. The design survives input transients up to 100 V as commonly required in communications equipment and protects the power distribution system with hiccup-mode fault protection.
National’s LM5035C PWM controller includes integrated 2 A half-bridge gate drivers and SyncFET outputs that control the secondary-side synchronous rectifier MOSFETs through the digital isolator. Dead time between the main and synchronous rectifier on/off transitions is adjustable with a single external resistor.
Silicon Labs’ ISOpro family of digital isolators employs digital RF technology to communicate data across an isolation barrier. Using the Si8420 digital isolator in place of pulse transformers eliminates numerous design issues such as duty cycle limitations and non-monotonic decay of output during shutdown. In addition, use of digital isolators improves efficiency and saves board space by eliminating the need for pulse transformers.
