    Quite small for a 3A device

    Involvement:Expert (understands the inner workings) - Ownership:less than 1 day

    Pros:
    Small (22x17 mm, 0.87"x0.67") Quite efficient chip, MP1584, with soft turn-on, current limit and adjustable switch frequency. (frequency is fixed to around 1MHz for this device) According to datasheet peak efficiency (around 88%) seems to be at 1 to 2A...
    Cons:
    Adjusting resistor very small. Frequency synchronization not possible. (Not really an issue in most cases)
