LT8410: Ultralow Power Boost Converters Only Require 8.5uA of Quiescent Current
Linear Technology announces the LT8410/-1 low noise micropower boost converters with integrated power switches, Schottky and catch diodes and output disconnect circuitry packaged in a 2mm x 2mm DFN package
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. Other features include integrated soft-start and overvoltage protection. The combination of the LT8410/-1’s 2mm x 2mm DFN package and tiny, low cost ceramic capacitors and inductors provides a very compact solution footprint.
The LT8410EDC and LT8410EDC-1 are both available from stock in an 8-lead 2mm x 2mm DFN package. Pricing starts at $1.75 each for 1,000-piece quantities.
