TLDR
In this article, an integrated circuit contains the gate drivers and the control components for constructing a DC power supply in any of the most popular converter topologies, including half-bridges.Abstract:
An integrated circuit contains the gate drivers and the control components for constructing a DC power supply in any of the most popular converter topologies. Multi-function elements in the control circuit minimize the area of the chip. The integrated circuit drives both the upper and lower switches of a half-bridge converter and separately regulates two power supply output voltages, one by pulse width modulation and the other by frequency modulation.read more
