Linear Technology has introduced a ride-through DC-DC voltage converter IC which can deal with a sudden loss of input voltage from a single supercapacitor energy source. The IC has a main buck regulator with a built-in boost converter for temporary backup, or ride-through, of VOUT during a sudden loss of input voltage. The device monitors VIN, VOUT and VCAP and

Linear Technology has designed a pair of 1.5W DC-DC converters with 2kVac galvanic isolation in a 9mm x 11.25mm x 4.92mm BGA (ball grid array) package. The LTM8057 and LTM8058 include an isolated transformer, control circuitry, power switches and a modest amount of input and output capacitance. Both devices will operate from an input voltage range of 3.1V to 31V,
