Product Summary
The LT1270ACT is a monolithic high power switching regulator. Identical to the popular LT1070, except for switching frequency (60kHz) and higher switch current, they can be operated in all standard switching configurations including buck, boost, flyback, and inverting. A high current, high efficiency switch of the LT1270ACT is included on the die along with all oscillator, control, and protection circuitry. Integration of all functions allows the LT1270ACT to be built in a standard TO-220 power package. This makes it extremely easy to use and provides "bust proof" operation similar to that obtained with 3-pin linear regulators. The LT1270ACT operate with supply voltages from 3.5V to 30V, and draw only 7mA quiescent current. By utilizing current-mode switching techniques, they provide excellent AC and DC load and line regulation.
