HIP6019B DC-DC Converter Application

Circuit

Figure 15 shows an application circuit of a power supply for a

microprocessor computer system. The power supply provides

the microprocessor core voltage (VOUT1), the I/O voltage

(VOUT2), the GTL bus voltage (VOUT3) and clock generator

voltage (VOUT4) from +5VDC and +12VDC. For detailed

information on the circuit, including a Bill-of-Materials and

circuit board description, see Application Note AN9800. Also

see Intersil’s web page (http://www.intersil.com).
