DescriptionThe LT1072CN8 is a monolithic, high-efficiency switching regulator. It can be operated in all standard switching configurations including: step-down (buck), step-up (boost), flyback, forward, inverting, and Cuk†. A high-current, high-efficiency switch is included in the package along with all oscillator, control, and protection circuitry. Integration of all functions allows the LT1072 to be built in standard 5-terminal KC or a KV packages and the 8-terminal P package. This makes it extremely easy to use and provides reliable operation similar to that obtained with 3-terminal linear regulators.
The LT1072CN8 operates with supply voltages from 3 V to 40 V. The LT1072HV, a high-voltage version of the LT1072, operates with supply voltages from 3 V to 60 V. These devices draw only 6 mA of quiescent current, deliver load power up to 20 W with no external power devices, and by utilizing current-mode switching techniques, provide excellent ac and dc input and output regulation.
The LT1072CN8 is much easier to use than the low-power control chips that are presently available and has many unique features that are not found on these chips. It uses an adaptive saturation-preventing switch drive to allow very-wide-ranging load currents with no loss in efficiency. An externally activated shutdown mode reduces total supply current to 50 mA typical for standby operation. Totally isolated and regulated outputs can be generated by using the optional flyback-regulation mode built into the LT1072CN8 without using optocouplers or extra transformer windings.If you want to know more information such as the electrical characteristics about the LT1072CN8,please download the datasheet in www.seekic.com or www.chinaicmart.com .
