4A Highly Integrated SupIRBuck^TM

IR3897

Single‐Input Voltage, Synchronous Buck Regulator

- 1 -

FEATURES

DESCRIPTION

integrated and highly efficient DC/DC regulator.

The onboard PWM controller and MOSFETs make

IR3897 a space‐efficient solution, providing accurate

power delivery.

The IR3897 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

IR3897 is a versatile regulator which offers

programmability of switching frequency and internal

current limit while operates in wide input and output

voltage range.

 Enable input with Voltage Monitoring Capability

The switching frequency is programmable from 300kHz

to 1.5MHz for an optimum solution.

 Thermally Compensated Current Limit with robust

hiccup mode over current protection

 Smart Internal LDO to improve light load and full load

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.
