Introduces a low power boost regulator with dual half-bridge in 3mm × 2mm DFN package that drives MEMS and piezo actuators.
The Linear Technology LT8415 integrates a step-up converter power switch, diode, and a complementary dual half-bridge driver into a single 12-pin, 3mm x 2mm DFN package. It is specifically designed to drive low current MEMS (micro-electro-mechanical systems) devices in automotive, military, medical, and consumer applications.
The device generates output voltages up to 40V from input sources ranging from 2.5V to 16V. The integrated half-bridge drivers are synchronously controlled by a single pin and feature N-channel and P-channel MOSFETs that never turn on simultaneously, ensuring high efficiency with minimal power dissipation throughout the load range.
The device generates output voltages up to 40V from sources ranging from 2.5V to 16V.
The regulator is integrated in a 12-pin, 3mm x 2mm DFN package.
The nodes revert to a high impedance state with 206MQ pull-down resistors to ground.
