01 August 2012 5A dc/dc converter generates positive or negative regulated voltage 5A dc/dc converter generates positive or negative regulated voltage Linear Technology has unveiled the LT3959 dc/dc converter for boost, SEPIC and inverting power supply applications. The device operates over an input voltage range of 2.5 to 40V, has an onboard 6A/40V power switch and is said to achieve up to 96% efficiency, making it suitable for industrial, automotive, medical and telecom applications. The LT3959 can generate either positive or negative regulated output voltage with its two internal voltage feedback error amplifiers and reference voltages. One set is for positive output voltages and the other is for negative output voltages, both off a single feedback pin. With an operating frequency from 100kHz to 1MHz, it is optimised for designers to choose a range of inductors and capacitors. The device's current mode control results in stable operation over a wide range of supply and output voltages and it supports designs using only ceramic capacitors, enabling a smaller solution size. The LT3959 operates from a -40 to 125°C temperature range and is available in a 5 x 6mm QFN-36 package.
