Description
The iP2005A is a fully optimized solution for high current
synchronous buck multiphase applications. Board space
and design time are greatly reduced because most of
the components required for each phase of a typical
discrete-based multiphase circuit are integrated into a
single 7.65mm x 7.65mm x 1.66mm power block. The
additional components required for a complete
multiphase converter are a PWM controller, the output
inductors, and the input and output capacitors.
• Microprocessor Power Supplies
• General DC/DC Converters
