IXD3263B755MR-G

Voltage Regulators - DC DC Switching Regulators Overview

The IXD3263B755MR-G is a synchronous step-down DC-DC converter manufactured by Zilog. It operates with an input voltage range up to 18V and provides a maximum output current of 0.5A. The device utilizes a PWM-only control scheme for regulation. It is housed in a SC-74A (SOT-753) surface-mount package, designed for compact power management applications requiring efficient voltage conversion.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific manufacturer documentation for the IXD3263B755MR-G to confirm pinout compatibility and thermal requirements. Ensure that the SC-74A footprint matches your PCB design constraints. Cross-reference the datasheet for absolute maximum ratings to prevent operational damage during integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed PWM control strategy is preferred over PFM or auto-switching modes. It is suitable for designs where input voltages do not exceed 18V and output currents remain within the 0.5A limit. Consider the SOT-753 package size for space-constrained layouts compared to larger regulator packages.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the Zilog IXD series of switching voltage regulators. It is distinct from the IXD3264 series, which supports both PFM and PWM modes, whereas this model is restricted to PWM operation only. Both share similar synchronous buck topologies but differ in control logic flexibility.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The IXD3264A755MR-G is a related synchronous step-down converter from the same manufacturer. However, it supports PFM/PWM auto-switching, differing from the PWM-only nature of the IXD3263B755MR-G. Verify if the additional mode flexibility impacts system stability before substitution.
