Easily Boost 12V to 140V with a Single Converter IC

Victor Khasiev - Applications Engineer Sep 28th 2015
Design Note 1033: Introduction Generating a high voltage from a much lower voltage presents a number of challenges for the classical single stage boost topology. For instance, the maximum duty cycle limitation of a boost controller may not allow the required step-up ratio. Even if it does, there is often a sharp decrease in ...

LTC3788 - High Efficiency Dual Boost Regulator with Independent Inputs

Victor Khasiev - Applications Engineer
Gabino Alonso - Strategic Marketing Engineer
Aug 27th 2014
Linear Technology offers a line of high performance multiple dual output synchronous boost converters. However, most of the datasheet contains examples of these controllers using the same input voltage source for both outputs. In some circumstances there may be a need to derive two different high output voltages from two separate ...

The Low Output Voltage Ripple Zeta DC/DC Converter Topology

Mathew Wich - Design Section Leader
Fu Sun - Design Engineer
Apr 28th 2014
In the world of switching DC/DC converters the Zeta topology is a lesser known relative of the SEPIC topology. Both converters provide a positive output voltage that can be greater than, equal to or less than VIN while avoiding the complexity and cost of a buck-boost converter. The Zeta converter however, has the advantage of ...
