LT1072CN8#PBF

LT1072 is a monolithic high power switching regulator. It 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. This device has many unique features not found even on the vastly more difficult to use low power control chips presently available. It uses an adaptive anti-sat switch drive to allow very wide ranging load currents with no loss in efficiency. Totally isolated and regulated outputs can be generated by using the optional “flyback regulation mode” built into the device, without the need for optocouplers or extra transformer windings. It is used in application like logic supply 5V at 2.5A, 5V logic to ±15V op-amp supply, offline converter upto 50W, battery upconverter, power inverter (+ to -) or (-to +), fully floating multiple outputs, driver for high current supplies etc.

• Wide input voltage range is 3V to 60V
• Low quiescent current is 6mA typical
• Internal 1.25A switch
• Very few external parts required
• Self-protected against overloads
• Operates in nearly all switching topologies
• Flyback-regulated mode has fully floating outputs, can be externally synchronized
• Shutdown mode draws only 50µA supply current
• Operating temperature is 0°C to 100°C
• Package style is 8-lead PDIP
