Product Summary

The LT1072CN8 is a monolithic high power switching regulator. The LT1072CN8 can be operated in all standard switching configurations including buck, boost, flyback, forward, inverting and Cuk. A high current, high efficiency switch is included on the die along with all oscillator, control, and protection circuitry. Integration of all functions allows the LT1072CN8 to be built in a standard 5-pin TO-3 or TO-220 power package as well as the 8-pin miniDlP. This makes it extremely easy to use and provides bust proof operation similar to that obtained with 3-pin linear regulators. The applications of the LT1072CN8 are: (1)Logic Supply 5V at 2.5A; (2)5V Logic to ±15V Op Amp Supply; (3)Offline Converter up to 50W; (4)Battery Upconverter; (5)Power lnverter (+ to –) or (– to +); (6)Fully Floating Multiple Outputs; (7)Driver for High Current Supplies.

Parametrics

LT1072CN8 absolute maximum ratings: (1)Supply Voltage: 40V; (2)Switch Output Voltage: 65V; (3)Feedback Pin Voltage (Transient, 1ms): ±15V; (4)Operating Junction Temperature Range: –55 to 150℃; (5)Storage Temperature Range: –65 to 150℃; (6)Lead Temperature (Soldering, 10 sec): 300℃.

Features

LT1072CN8 features: (1)Available in MiniDiP, TO-220, and TO-3 Packages; (2)Wide Input Voltage Range 3V to 60V; (3)Low Quiescent Current—6mA; (4)Internal 1.25A Switch; (5)Very Few External Parts Required; (6)Self-Protected Against Overloads; (7)Operates in Nearly All Switching Topologies; (8)Shutdown Mode Draws Only 50μA Supply Current; (9)Flyback-Regulated Mode has Fully Floating Outputs; (10)Can be Externally Synchronized.
