12A Highly Integrated SupIRBuck

IR3894

Single‐Input Voltage, Synchronous Buck Regulator

- 1 -`

FEATURES

DESCRIPTION

integrated and highly efficient DC/DC regulator.

The onboard PWM controller and MOSFETs make

IR3894 a space‐efficient solution, providing accurate

power delivery.

The IR3894 SupIRBuck^TMis an easy‐to‐use, fully

 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

 Enhanced Line/Load Regulation with Feed‐Forward

 Programmable Switching Frequency up to 1.5MHz

 Internal Digital Soft‐Start/Soft‐Stop

IR3894 is a versatile regulator which offers

programmable switching frequency and the fixed

internal current limit

 Enable input with Voltage Monitoring Capability

The switching frequency is programmable from 300 kHz

to 1.5MHz for an optimum solution.

 Thermally Compensated Current Limit with robust

hiccup mode over current protection

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.

 Smart internal LDO to improve light load and full load

efficiency

 External Synchronization with Smooth Clocking

 Enhanced Pre‐Bias Start‐Up

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

margining capability

APPLICATIONS

 Netcom Applications

 Vp for Tracking Applications ((Source/Sink Capability

+/‐12A)

 Embedded Telecom Systems

 Server Applications

 Integrated MOSFET drivers and Bootstrap Diode

 Thermal Shut Down

 Storage Applications

 Programmable Power Good Output with tracking

capability

 Distributed Point of Load Power Architectures

 Monotonic Start‐Up

 Operating temp: ‐40^oC < Tj < 125^oC

 Small Size: 5mm x 6mm PQFN

 Lead‐free, Halogen‐free and RoHS Compliant
