Product Details

The MAX17019 evaluation kit (EV kit) presents the MAX17019 high input-voltage quad-output controller in a typical application setup. The EV kit operates from a 5.5V to 38V input range.

High-voltage controller A is used to generate a 5V rail that serves as supply for the other three rails. These rails are generated by two switching converters (rails B and C), and one push-pull linear regulator (rail D). The supplies for converters B and C and regulator D are accessible but must be less than 6V.

The MAX17019 also has an internal fixed 5V linear regulator capable of supplying 50mA. The EV kit operates at 0.5MHz (VOUTA and VOUTC) and at 1MHz switching frequency (VOUTB). The EV kit has superior line- and load-transient response.
