Linear Technology LT1072
the LT1072 by factoring in the lower switch current rating. It can be operated in all standard switching configurations including buck, boost, flyback, forward, inverting and “Cuk”. Integration of all functions allows the LT1072 to be built in a standard 5-pin TO-3 or TO-220 power package as well as the 8-pin miniDlP.| Part No. | LT1072 |
