Description
The iP2005A is a fully optimized solution for high curr ent
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.
iPOWIR Technology offers designers an innovative
board space saving solution for applications requiring
high power densities. iPOWIR technology eases design
for applications where component integration offers
benefits in performance and functionality. iPOWIR
technology solutions are also optimized internally for
layout, heat transfer, and component selection.
Applications
• High Frequency, Low Profile DC-DC
• Multi-phase Architectures
• Low Duty Cycle, High Current solutions
• Microprocessor Power Supplies
• General DC/DC Converters
