Title
A Highly Efficient Interleaved Dc-Dc Converter Using Coupled Inductors In Gaas Technology
Abstract
This paper presents a high power efficiency DC-DC buck converter in Gallium Arsenide technology targeting integrated power amplifier modules. The buck converter adopts an interleaved structure with negatively coupled inductors. Analysis of the effect of coupling on the steady state and transient response of the converter is given. The coupling factor is selected to achieve a maximum power efficiency for a given duty cycle with a minimum penalty on current ripple performance. The DC-DC converter is implemented in 0.5 mu m GaAs pHEMT process and occupies 2.7x2.7mm(2) without the output network. It converts 4.5V input to 3.3V output for 1A load current under 250MHz switching frequency with a power efficiency of 86.1%
