DC2897A must be read in conjunction with the data sheet.
The LTC7819 data sheet provides a complete description of the part, operational details, and applications information. Optional spread spectrum modulation to reduce EMI, a PLLIN pin to synchronize to an external clock, optional DCR sensing footprints, an EXTV CC pin to reduce losses in the controller and optional footprints to parallel two or three channels. Typical applications include automotive, transportation, industrial, military and avionics systems.įeatures of the DC2897A include pin selectable light load operating modes of forced continuous mode, pulse-skipping and Burst Mode ® operation.
Each rail uses a 3mΩ sense resistor to sense the current and provides optional footprints for DCR sensing. It provides outputs of 3.3V at 12A, 8.5V at 10A and 5.0V at 12A over an input voltage range of 10V to 36V with a switching frequency of 380kHz. The circuit is optimized for high efficiency. Demonstration circuit 2897A is a low I Q, triple output, synchronous step-down supply featuring the LTC7819.
