Dual-output step-down DC/DC controller featuring a 320kHz switching frequency. This surface-mount integrated circuit offers two outputs with a minimum output voltage of 0.7V and a typical output current of 1.7A per output. Housed in a 20-pin SOP package with gull-wing leads, it operates from an 8V to 15V input voltage range and has a maximum supply current of 5.3mA. Designed for lead-frame SMT mounting, the plastic small outline package measures 13mm x 7.6mm x 2.35mm with a 1.27mm pin pitch. Operating temperature range is -40°C to 85°C.
