Product Details
The MAX1522 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that contains two separate step-up switching controller circuits. The first circuit (left side) utilizes the MAX1524, is configured for +5V output, and can deliver up to 1A of current. The MAX1524 supply pin is bootstrapped to the output. The second circuit (right side) utilizes the MAX1522, is configured for +12V output, and can deliver up to 200mA of current with the input voltage as low as +2.7V.
The MAX1522 and MAX1524 feature soft-start and fault-detect. The EV kit allows the user to set the on-time of the N-channel MOSFETs to either 0.5µs or 3µs.
