BASIC APPLICATION

Figure 1: IR3899 Basic Application Circuit

DESCRIPTION

The IR3899 SupIRBuck

TM is an easy‐to‐use, fully integrated

and highly efficient DC/DC regulator. The onboard PWM

controller and MOSFETs make IR3899 a space‐efficient

solution, providing accurate power delivery.

IR3899 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
