A power supply incorporating the DC/DC controller can convert a 4 V to 60 V input supply to a regulated output ranging from 1.23 V to 36 V in applications such as industrial, 12 V and 42 V automotive, heavy equipment, avionics and telecom power systems. The controller has a 200 kHz fixed operating frequency. Prices start at $5.94 each for 1,000 piece quantities.
