Working Principle

The IR3894MTR1PBF is a synchronous buck converter based switching voltage regulator. It operates in PFM mode and is capable of achieving a high efficiency even at very light load current. The IR3894MTR1PBF uses a variable frequency architecture based on a constant on-time control scheme to generate an output voltage from an input voltage that is higher or lower than the output voltage.The IR3894MTR1PBF is designed with a DSP controller that reduces reference voltages, improves light load efficiency, and saves power losses. It also includes output voltage tracking and a wide input voltage range with low ripple-noise switching. Furthermore, the regulator includes over current and short-circuit protection.The IR3894MTR1PBF regulator is available in several different package options and can be used with both input transformers and inductors. A PGOOD (power good) signal is used to indicate when power is good and is also used to protect against over-voltage conditions.

Conclusion

In conclusion, the IR3894MTR1PBF is a high-performance, low-external-parts-count synchronous buck converter based switching voltage regulator suitable for automotive, audio/video, power management, control/telemetry, telecom, battery charging and other digital PCB applications offering best-in-class performance, superior load and line regulation, low standby current and thermal shutdown protection. This device is optimized to reduce external component count, board space, and cost and is available in several different package options to meet the requirements of high performance, automotive, and medical equipment.
