Analog Devices LTC3786EMSE#PBF LTC3786EMSE#PBF DC/DC Controller Synchronous Boost 4.5V to 38V 1 Output 96% Duty Cycle 760kHz MSOP-EP-16
LTC®3786 is a high performance synchronous boost converter controller that drives all N-channel power MOSFETs. Synchronous rectification increases efficiency, reduces power losses and eases thermal requirements, allowing this to be used in high power boost applications. When biased from the output of the boost converter or another auxiliary supply, this can operate from an input supply as low as 2.5V after start-up. The 55µA no-load quiescent current extends operating run time in battery-powered systems. The operating frequency can be set for a 50kHz to 900kHz range or synchronized to an external clock using the internal PLL. This also features a precision 1.2V reference and a power good output indicator. The SS pin ramps the output voltage during start-up. The PLLIN/MODE pin selects among Burst Mode® operation, pulse-skipping mode or continuous inductor current mode at light loads. Typical applications are medical devices, high voltage battery-powered systems.
