The DC770C is a demonstration board featuring LT3782AEFE constant frequency current mode boost controller. The LT3782AEFE is a current mode two phase step up DC to DC converter controller. Its high switching frequency (up to 500KHz) and two phase operation reduce system filtering capacitance and inductance requirements. The DC770C demonstration board operates over 10V to 28V input and provides 4A of output current at 50V output. The 250KHz constant frequency operation results in a small and efficient circuit. The converter provides high output voltage accuracy (typically ±3%) over wide load range with no minimum load requirement. The demonstration circuit can be easily modified to generate different output voltages.
