LT1072CT#PBF

LT®1072 is a monolithic high power switching regulator. It can be operated in all standard switching configurations including buck, boost, flyback, forward, inverting and “Cuk”. This makes it extremely easy to use and provides bust proof operation similar to that obtained with 3-pin linear regulators. By utilizing current-mode switching techniques, it provides excellent AC and DC load and line regulation. It uses an adaptive anti-sat switch drive to allow very wide ranging load currents with no loss in efficiency. An externally activated shutdown mode reduces total supply current to 50µA typical for standby operation. Totally isolated and regulated outputs can be generated by using the optional flyback regulation mode, without the need for optocouplers or extra transformer windings. Applications are logic supply 5V at 2.5A, 5V logic to ±15V op amp supply, offline converter up to 50W, battery upconverter, fully floating multiple outputs, driver for high current supplies.

• Deliver load power up to 20watt with no external power devices
• Wide input voltage range from 3V to 60V
• Low quiescent current of 6mA
• Internal 1.25A switch
• Very few external parts required
• Self-protected against overloads
• Operates in nearly all switching topologies
• Shutdown mode draws only 50µA supply current
• Can be externally synchronized
• 5-lead TO-220 package
