Typical Application - 2-Phase Converter
Figure 1 shows a 2-Phase Synchronous Buck Converter
circuit used to provide “CORE” voltage regulation for the
Intel Pentium IV mobile processor using IMVP-IV™ and
IMVP-IV+™ voltage positioning.
The ISL6217A PWM controller can be configured for two or
one channel operation, and the ISL6217A can change the
number of power channels in operation, dynamically. The
number of channels of operation can be changed through

the PWRCH pin. The ISL6217A can be configured for two
channel operation in “Active” mode and one channel
operation in “Deep” and “Deeper Sleep” modes through logic
connections to the PWRCH pin. The following configuration
uses two channel operation in “Active” mode and one
channel operation in “Deep” and “Deeper Sleep” modes.
The circuit shows pin connections for the ISL6217A PWM
controller in the 38 lead TSSOP package.
