DESCRIPTION

The IR3898 SupIRBuck

TM is an easy-to-use, fully

integrated and highly efficient DC/DC regulator.

The onboard PWM controller and MOSFETs make

IR3898 a space-efficient solution, providing accurate

power delivery.

IR3898 is a versatile regulator which offers

programmable switching frequency and the fixed

internal current limit while operates in wide input and

output voltage range.

The switching frequency is programmable from 300kHz

to 1.5MHz for an optimum solution.

It also features important protection functions, such as

Pre-Bias startup, thermally compensated current limit,

over voltage protection and thermal shutdown to give

required system level security in the event of fault

conditions.

APPLICATIONS

 Netcom Applications

 Embedded Telecom Systems

 Server Applications

 Storage Applications

 Distributed Point of Load Power Architectures
