The high efficiency monolithic switching regulator integrates a 5 A power switch and control circuitry for buck, boost, inverting, and flyback converter topologies. It operates from a 3.5 V to 30 V supply range and uses a 100 kHz oscillator. The regulator uses a 1.244 V feedback reference and provides current limiting for the internal switch. Package options include 5-lead TO-220 and 5-lead DD Pak variants.
