Voltage Regulators - DC DC Switching Regulators datasheet and documents for IR3823MTR1PBF

IR3823MTR1PBF

Voltage Regulators - DC DC Switching Regulators Overview

The IR3823MTR1PBF is a single-output adjustable synchronous buck switching regulator from Infineon Technologies' SupIRBuck series. It delivers up to 3A output current with an input voltage range of 5.5V to 21V and an adjustable output voltage from 0.6V to 18.06V. The device operates at a fixed switching frequency of 300kHz, though it supports jittering up to 1.5MHz for EMI reduction. Packaged in a 15-PowerVFQFN (5x6mm) surface-mount footprint, it functions within a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates high-side and low-side power MOSFETs with synchronous rectification for high efficiency.
Utilizes EasyCOT control topology for fast transient response and simplified external component requirements.
Features integrated bootstrap diode and gate drive circuitry to minimize external bill of materials.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix MTR1PBF against official Infineon documentation to confirm reel packaging and lead-free status. Confirm availability as the part may be discontinued or subject to limited supply constraints. Ensure compatibility with moisture sensitivity level requirements during assembly processing.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact single-phase solution is required for moderate current loads up to 3A. The wide input voltage range suits applications powered by 12V or 24V buses. Consider the 300kHz fixed frequency for predictable EMI filtering compared to variable frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This regulator belongs to the SupIRBuck family, which integrates power stages into small packages to reduce solution size. The IR3823 variant specifically targets applications needing a balance between performance and board space, utilizing the PowerVFQFN package for thermal management.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct pin-compatible upgrades within the IR38xx series. Verify if newer generations offer improved efficiency or extended operating temperatures while maintaining the same footprint and control interface.
