dc1260a-b DC1260A-B LTC3539EDCB-2 Demo Board | 2MHz, 0.7V ≤ VIN ≤ 5.5V, VOUT = 1.8V/3.3V/5V @ 0.9A Demonstration circuits 1260A-A and 1260A-B are high-efficiency synchronous boost converters capable of operating with an input voltage range from 0.7V to 5.5V using the LTC3539 and LTC3539-2 respectively. The 2 × 3 mm DFN thermally enhanced package with a 1MHz switching frequency (2MHz for the -2 part) and the 2A internal switches provide a very tiny overall solution. Jumpers are provided for selecting 1.8V, 3.3V or 5V at the output and the circuit can provide 300mA at 3.3V from a 1.5V input and can provide up to 900mA depending on the input and output voltage used.
