• Description: High Frequency Synchronous Buck Optimized Lga Power Stage
• Manufacturer: International Rectifier Corp.

Optimized EMI Feature
The iP2005A is designed for low Electromagnetic Interference (EMI) which minimizes power
loss and space, and simplifies system design by eliminating the need for external snubber
circuits. These benefits are achieved by optimizing the internal component layout, integrating
bypass filters and implementing active clamp circuitry as a means of reducing switching node
voltage ringing; which is one of main sources of EMI. The figures above show waveform
comparisons of switching node voltages of the previous generation iP2003A product and
iP2005A under equivalent operation conditions.
