    • Product Details

    The MAX1947 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board demonstrating the low-voltage, skip-mode boost converter. The EV kit provides a 1.8V output voltage capable of sourcing 270mA (typ) load current from a 0.7V to 3.6V input source. The MAX1947 features skip mode to optimize efficiency and battery life. It also contains internal MOSFETs for lower cost and size. The 1.2MHz (max) switching frequency allows the use of small external components. The MAX1947 EV kit is fully assembled and tested. The MAX1947 EV kit can be used to evaluate the MAX1947ETA25, MAX1947ETA30, and MAX1947ETA33 with no PC board modification.
