Switching Controllers

Analog Devices’ family of synchronous switching controllers provides high conversion efficiency with voltage rails down to 0.6 V with up to 50 A output. These products are highly programmable and deliver performance that is tailored to the application's requirements.
Available features include single and dual channels, precision enable input, programmable soft-start, undervoltage lock out (UVLO), programmable current limit, voltage margining capability, tracking, sequencing, frequency synchronization, 3 V to 24 V input voltage range, power good flag, and output accuracy to 0.5% at 25°C.
