The LTC3125 is 1.6MHz, current mode, synchronous boost DC/DC converter with an accurate and programmable average input current limit. Its internal 1.2A switches can deliver output voltages as high as 5.25V from an input voltage range of 1.8V to 5.5V, making it ideal for Li-Ion/Polymer, 3.3V PC card slot or multicell alkaline/NiMH applications. The LTC3125 can deliver up to 500mA of continuous output current (at 5V) from a 3.3V input. The LTC3125’s average input current limit can be programmed between 200mA and 1000mA with ±5% accuracy. The accurate adjustable current limit combined with an output reservoir capacitor makes the LTC3125 ideal for applications such as GSM and GPRS cards which demand 2A or higher current pulses from a power-limited input source…
