1.1MHz, 25V Dual Step-Down DC/DC Converter Delivers 1.6A per Channel from a 5mm x 4mm DFN Package
The LT3506 and LT3506A’s low VCESAT (210mV @1A) internal switches offer efficiencies of up 88%, minimizing thermal constraints and maximizing battery run-time. Low voltage outputs are easily attended due to an internal reference of 0.80V. Each channel has independent shutdown and soft-start pins as well as independent power good indicators to ease power sequencing. The channels switch 180 degrees out of phase with respect to the other, reducing input ripple and minimizing capacitance needs. Internal cycle-by-cycle current limit provides protection against shorted outputs while soft-start eliminates input current surge during start up. The low current (
