DESCRIPTION: half-brick dc-dc converter
description
The VHB150W series of DC-DC converters
are designed for high reliability
applications, featuring over-temperature
protection, and 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.
