LT1082 Datasheet PDF

●The LT1082CN8#PBF is a monolithic high-voltage Switching Regulator can be operated in all standard switching configurations including buck, boost, flyback, forward and inverting. A 1A high efficiency switch is included on the die along with all oscillator, control and protection circuitry. The LT1082 operates with supply voltage from 3 to 75V, switch voltage up to 100V and draws only 4.5mA quiescent current. It can deliver load power up to 20W with no external power devices. By utilizing current-mode switching techniques, it provides excellent AC and DC load and line regulation. An externally activated shutdown mode reduces total supply current to 120µA typical for standby operation. Totally isolated and regulated outputs can be generated by using the optional isolated flyback regulation mode built into the LT1082, without the need for optocouplers or extra transformer windings.

● Isolated flyback regulation mode for fully floating outputs

● Can be externally synchronized

● Internal 1A switch

● Shutdown mode draws only 120µA supply current
