Description
The kB3429 is high efficiency synchronous, step-up DC/DC converters optimized to provide a high efficient solution to medium power systems. The devices work under the input voltage between 0.6V and 4.4V with a 1.5MHz fixed frequency switching. These features minimizes overall solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors.
