Switching Controllers

Switching controllers utilize external power MOSFETs to offer design engineers the flexibility to set output current levels and limits, that typically range from 5 A to 25 A per channel for synchronous designs. 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, Under Voltage Lock Out (UVLO), programmable current limit, voltage margining capability, tracking, sequencing, frequency synchronization, from 3 V to 24 V input voltage range, power good flag, and output accuracy to 0.5% at 25°C.
