IR38062MTRPBF

Voltage Regulators - DC DC Switching Regulators Overview

The IR38062MTRPBF is a single-phase synchronous buck converter from Infineon's SupIRBuck series, designed for point-of-load applications. It integrates high-side and low-side power MOSFETs with a voltage-mode controller in a compact 34-pin PowerVFQFN package. The device supports an input voltage range of 1.2 V to 21 V and delivers up to 15 A output current. Output voltage is adjustable from 0.5 V to 18.375 V via an external resistor divider or digital interface. Operating frequencies are programmable between 400 kHz and 1.5 MHz. It includes an internal LDO bias supply and features comprehensive protection mechanisms including overvoltage, overcurrent, and thermal shutdown.

• Industrial equipment needing programmable DC-DC conversion
• Telecommunications infrastructure power distribution networks

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix MTRPBF confirms the tape-and-reel packaging format required for automated assembly processes. Confirm RoHS compliance status matches project environmental regulations. Ensure the 34-pin PowerVFQFN footprint aligns with existing PCB layout constraints before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-phase solution with digital control capabilities is preferred over multi-phase architectures for moderate current loads. The integrated MOSFETs reduce board space compared to discrete designs. Verify that the 1.2 V minimum input voltage requirement suits the system's available rail, as some variants support lower inputs.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to Infineon's SupIRBuck family of highly integrated power stages. It replaces older discrete buck solutions by combining the controller, drivers, and power switches into one module. The MTRPBF designation indicates the standard commercial-grade temperature range and reel packaging suitable for high-volume manufacturing environments.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for IR38062M without the trailing suffix if bare die or different packaging is needed. Consider IR38064MTRPBF for higher current requirements up to 35A within the same package family.
