Demonstration circuit 2169A is a dual monolithic step-down DC/DC switching regulator featuring the LT8616. The LT8616 is a high efficiency, high speed, dual synchronous monolithic step-down switching regulator that consumes only 6.5μA of quiescent current with both channels enabled. The demo circuit is designed for 5V, 1.5A and 3.3V, 2.5A outputs. Both channels contain all switches and necessary circuitry to minimize the external components and solution size. Fast minimum ON time of 35ns enables high VIN to low VOUT conversion at high switching frequency. Independent input voltage, feedback, soft-start and power good pins for each channel simplify complex power supply tracking/sequencing requirements.
