9A Highly Integrated SupIRBuck^TM

IR3899

Single‐Input Voltage, Synchronous Buck Regulator

- 1 -

FEATURES

DESCRIPTION

The IR3899 SupIRBuck^TMis 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.

 Single 5V to 21V application

 Wide Input Voltage Range from 1.0V to 21V with

external Vcc

 Output Voltage Range: 0.5V to 0.86× Vin

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.

 Enhanced Line/Load Regulation with Feed‐Forward

 Programmable Switching Frequency up to 1.5MHz

 Internal Digital Soft‐Start/Soft‐Stop

The switching frequency is programmable from 300kHz to

1.5MHz for an optimum solution.

 Enable input with Voltage Monitoring Capability

 Thermally Compensated Current Limit with robust

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.

hiccup mode over current protection

 Smart internal LDO to improve light load and full

load efficiency

 External Synchronization with Smooth Clocking

 Enhanced Pre‐Bias Start‐Up

APPLICATIONS

 Netcom Applications

 Precision Reference Voltage (0.5V+/‐0.5%) with
