Linear Technology Corporation announces the "H-Grade" version of the LT1936. The LT1936 is a 36 V, current mode PWM step-down DC/DC converter with an internal 1.9 A power switch, packaged in an 8-lead thermally enhanced MSOP package. The H grade version operates up to a junction temperature of 150° C, compared to the "E"- and "I"-grade versions' 125° C maximum junction temperature. The H grade parts are both tested and guaranteed to the maximum junction temperature of 150° C. They are suited for automotive and industrial applications which are subjected to high ambient temperatures. The LT1936's input range of 3.6 V to 36 V makes the LT1936 appropriate for regulating power from a wide variety of sources, including unregulated wall transformers, 24 V industrial supplies and automotive batteries.
