Five-Output 25mA/LED Driver with Two LDOs Operates Down to 2.7V

MILPITAS, CA, (PresseBox) - Linear Technology Corporation announces the LTC3230, an integrated white LED driver with dual LDO regulators for driving Main and Sub LED displays and supplying low-voltage system rails in portable electronic devices, all in a compact 3mm x 3mm QFN package. The LTC3230 drives up to five 25mA LED current sources, providing 125mA of total output current, and integrates two 200mA LDOs with separate enables and pin-selectable output voltages as low as 1.2V and 1.8V, respectively. The LTC3230’s 2.7V to 5.5V input voltage range has been optimized for single cell Li-Ion/Polymer applications. Efficiencies when driven from a Li-Ion battery (3.6V nominal) reach 91% with quiescent current of only 400uA, maximizing battery run-time. The LTC3230 requires only six small capacitors and one resistor to create a tiny, low profile (
