High Voltage, Current Mode Switching Regulator Controller with Programmable Operating Frequency DESCRIPTIO
The LT®3844 is a DC/DC controller used for medium power, low part count, high efficiency supplies. It offers a wide 4V-60V input range (7.5V minimum startup voltage) and can implement step-down, step-up, inverting and SEPIC topologies. The LT3844 includes Burst Mode operation, which reduces quiescent current below 120μA and maintains high efficiency at light loads. An internal high voltage bias regulator allows for simple biasing. Additional Features include current mode control for fast line and load transient...
