dc2067a DC2067A Demonstration circuit 2067A is a synchronous inverting converter (CUK topology) featuring the LT8710 switching controller. It regulates a –5V, 6A output from a 4.5V to 28V input source, and operates at 300kHz switching frequency. The LT8710 features simple negative or positive output voltage programming. The DC2067 programs a –5V output with a single resistor. DC2067A LT8710EFE Inverting Demo Board | 4.5V ≤ VIN ≤ 28V; VOUT: -5V @ 6A
