The ISL6269AEVAL2Z evaluation board is used to demonstrate the performance of the ISL6269A single-phase synchronous buck PWM controller featuring Renesas' Robust Ripple Regulator (R3™) technology. The ISL6269AEVAL2Z is shipped with the ISL6269A controller installed. An on-board dynamic-load generator is included for evaluating the transient-load response that applies a 2.5ms pulse of 250mΩ across VOUT and GND every 30ms.

The ISL6269A IC delivers truly superior dynamic response to input voltage and output load transients. Integrated MOSFET drivers and a bootstrap diode result in fewer components and a smaller implementation area.
