Subcategories

These powerful synchronous switching boost regulators efficiently generate higher output voltages (up to 20 V) from input voltages as low as 2.9 V while using an input current as high as 8 A. They feature reverse voltage protection, and unlike most boost regulators, they offers a true shutdown option that turns off power to the load.

These switching boost regulators efficiently generate higher output voltages (up to 30 V) from input voltages as low as 2.9 V while using an input current as high as 5 A. They feature reverse voltage protection.
