LTC7803 Synchronous Step-Down Controllers

Analog Devices Inc. LTC7803 Synchronous Step-Down Controllers are high-performance, 100% duty cycle capable, synchronous step-down DC/DC switching regulator controllers that drive 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. Analog Devices LTC7803 Synchronous Step-Down Controllers operate from a wide 4.5V to 40V input supply range.
