Demonstration circuit 613 is a 3A, 500kHz, stepdown converter with 100uA quiescent current featuring the LT3435IFE. It produces 5V at 2A from an input range of 6.75V to 28V continuous, and can survive input transients up to 60V. The demonstration circuit includes a shutdown control, synchronization from 500kHz to 700kHz and a programmable power good indicator. The LT3435 is a 500kHz monolithic buck switching regulator that accepts input voltages up to 60V. A high efficiency 3A, 0.1W switch is included on the die along with all the necessary oscillator, control and logic circuitry. Current mode topology is used for fast transient response and good loop stability. Innovative design techniques along with a new high voltage process achieve high efficiency over a wide input range. Efficiency is maintained over a wide output current range by employing Burst Mode® operation at low currents, utilizing the output to bias the internal circuitry, and by using a supply boost capacitor to fully saturate the power switch.
