The SGM6606 is a high current, synchronous step-up regulator with a programmable input or output current limit. It is ideal to prevent the output current of SGM6606 from overloading or it limits the input current from battery or power source in standard interface, such as PCMCIA, PCI-E. The SGM6606's internal compensation is optimized for the large output capacitors needed to support the output voltage during large load pulses. The SGM6606 can set the loading current.
The output voltage may be programmed from 3.0V to 5.0V by external resistor divider. Light load switching frequency modulation and low quiescent current maintain high efficiency performance for light load mode conditions.
The output or input current limit can be set by an external current sensing resistor RSENSE. The SGM6606 includes an internal over-voltage protection and a power- good indication. SGM6606 has an internal soft-start circuit to reduce the input peak current.
