Integrated-Power Buck Converter Controller with Synchronous Rectification
The HIP5020 is a high-efficiency, buck converter controller with synchronous rectification and integral power MOSFETs. Integrated current sensing eliminates the external resistor and saves power. The controller bines two methods of regulation: Current mode control for outstanding regulation response to large signal load transients, and Hysteretic mode control for high efficiency at low output currents. The HIP5020 controller offers a high degree of flexibility. Small ponents set the switching frequency, the soft-start interval and the load current boundary between...
