Schottky and catch diodes and output disconnect circuitry packaged in a 2mm x 2mm DFN package. The LT8410/-1 use a unique design scheme, requiring only 8.5uA of quiescent, which is further reduced to 0uA in shutdown. Integrated high value (12.4M/0.4M) output feedback divider resistors enable the LT8410/-1 to regulate a 16V output with no load with less than 30uA of quiescent current. Very small switch current limits (25mA for the LT8410 and 8mA for the LT8410-1) enable these converters to operate very efficiently from high impedance sources, such as coin cell batteries without any inrush current limitations.
The LT8410/-1’s wide 2.6V to 16V input voltage range enables them to operate from single cell Li-Ion batteries up to fixed 12V input rails, delivering outputs up to 40V. The output voltage can be adjusted dynamically by driving the FBP pin with an external voltage source. The LT8410 can deliver over 8mA of output current at 16V from a single Li-Ion cell making it ideal for applications such as precision sensor or biasing power. Both parts use a unique control technique that delivers efficiencies as high as 88% and low output ripple (<10mVPK-PK) over a wide load current range.
