1 / 10 page rev. page date page date DESCRIPTION: half-brick dc-dc converter 1 of 10 04/2011 20050 SW 112th Ave. Tualatin, Oregon 97062 phone phone 503.612.2300 fax www.v-infinity.com fax 503.612.2383 PART NUMBER: VHB75W features ·37.5-75W isolated output ·Efficiency to 85% ·300 kHz switching frequency ·regulated output ·continuous short circuit protection ·industry standard half-brick size ·remote on/off ·over-temperature protection ·over-current protection description The VHB75W series of DC-DC converters are designed for high reliability applications, featuring over-temperature protection, over-current protection. The wide 4:1 input range (9-36V or 18-75V) is very useful to stabilize an input source like batteries in various discharging and charging conditions. Additionally, high efficiency, fast response, tight regulations, remote sense and remote On/Off control make these converters very useful in many applications.
