DC1537A - LT3992EFE Demo Board | Dual Buck with Tracking, 7V ≤ VIN ≤ 60V, Vout1 = 5V @ 2A, Vout2 = 3.3V @ 2A

The demo circuit 1537A is a dual current mode PWM step-down DC/DC converter featuring LT®3992. The demo circuit is designed for 5V and 3.3V outputs from a 7V to 60V input. The current capability of each channel is up to 3A when running individually and 2A when both are sourcing the same current without special heat sinking. Individual soft-start, current limit, comparator, input voltage for each output as well as frequency division and synchronous and clock output functions simplify the complex design of dual-output power converters
