LTC7804 Low IQ Synchronous Boost Controller

Analog Devices LTC7804 Low I_Q Synchronous Boost Controller is a high-performance synchronous boost DC/DC switching regulator controller that drives an all N-channel power MOSFET stage. Synchronous rectification increases efficiency, reduces power losses, and eases thermal requirements. A constant frequency current mode architecture allows a phase-lockable switching frequency of up to 3MHz. The LTC7804 operates from a wide 4.5V to 40V input supply range. When biased from the boost converter output, the LTC7804 can operate from an input supply as low as 1V after startup.
