Linear Technology has a low noise micropower boost converter with integrated dual half-bridge switches.

The LT8415 draws just 10.5µA of quiescent current, which is further reduced to 0uA in shutdown.

Integrated high value (12.4M/0.4M) output feedback divider resistors enable the LT8415 to regulate a 16V output with less than 70uA of total input current.

Its very small 25mA switch current limit means it can operate efficiently from high impedance sources, such as coin cell batteries without any inrush current limitation, said the supplier.

Integrated N-channel and P-channel mosfets in each half-bridge are synchronously controlled by a single input pin, and never turn on at the same time maximizing system reliability for applications such as MEMs relays.

The internal mosfets are sized to drive capacitive loads ranging from a few pF to several nF without issue.

The chip integrates the main switch, half-bridge switches, Schottky diodes and output disconnect on a single die, packaged in a 2x3mm DFN.
