LT puts supercapacitor power back-up on a chip

Linear Technology has put the whole of a supercapacitor power back-up system on one chip. Rated at 2A, it will back-up a voltage rail (Vsys) between 1.71 and 5.25V. Key to the chip, called LTC3110, is a 1.2MHz four-switch bi-directional dc-dc converter that both charges the capacitor and can also extract almost all of the
