The LTC7821IUH#TRPBF from Analog Devices Inc. is a hybrid step-down synchronous controller designed for high efficiency and low noise operation. It utilizes a proprietary architecture merging a soft switching charge pump topology with a synchronous step-down converter.
Key electrical specifications include a wide input voltage range of 10V to 72V (80V ABS Max) and a phase-lockable fixed switching frequency adjustable from 200kHz to 1.5MHz. The controller offers ±1% output voltage accuracy and supports RSENSE or DCR current sensing. It is programmable for Continuous Conduction Mode (CCM), Discontinuous Conduction Mode (DCM), or Burst Mode operation.
This controller is suitable for applications such as intermediate bus converters, high current distributed power systems, and telecom, datacom, and storage systems. It can be easily paralleled for higher output currents due to its accurate current sharing capability and frequency synchronization function.
The device is available in a 32-pin (5mm × 5mm) QFN package, suitable for surface mounting.
The input voltage range is 10V to 72V, with an absolute maximum rating of 80V.
The phase-lockable fixed switching frequency can be set from 200kHz to 1.5MHz.
The output voltage accuracy is ±1%.
It is supplied in a 32-pin (5mm × 5mm) QFN package.
The product is RoHS3 Compliant.
The Moisture Sensitivity Level is 1 Unlimited.
The product is REACH Unaffected.
