The IR3831 SupIRBuck TM is an easy-to-use, fully
integrated and highly efficient DC/DC regulator.
The MOSFETS co-packaged with the on-chip
PWM controller make IR3831 a space-efficient
solution, providing accurate power delivery for
DDR memory applications.
IR3831 is configured to generate termination
voltage (VTT) for DDR memory applications.
IR3831 offers programmability of start up time,
switching frequency and current limit while
operating in wide input and output voltage range.
The switching frequency is programmable from
250kHz to 1.5MHz for an optimum solution.
It also features important protection functions,
such as Pre-Bias startup, hiccup current limit and
Applications
thermal shutdown to give required system level
security in the event of fault conditions.
