IXD3263B755ER-G

Voltage Regulators - DC DC Switching Regulators Overview

The IXD3263B755ER-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 fixed output voltage of 0.75V. The device supports a continuous output current of 0.5A. Unlike the IXD3264 variant, this model functions exclusively in Pulse Width Modulation (PWM) mode without auto-switching capabilities.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Synchronous rectification architecture for improved efficiency
• Fixed PWM operation mode for stable regulation
• Integrated power switch design

Voltage Regulators - DC DC Switching Regulators Applications

• Portable electronic devices requiring low voltage rails
• Embedded systems with 18V input sources
• Battery-powered equipment needing efficient step-down conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'ER-G' against the manufacturer's official documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the application circuit matches the PWM-only control scheme, as this part lacks the auto-PFM/PWM switching feature found in other series variants.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 0.75V output at 0.5A is required from an 18V source. Choose this part over the IXD3264 if constant frequency PWM operation is preferred over adaptive PFM/PWM modes. Confirm that the thermal requirements of the package can handle the expected load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the Zilog IXD326x series of synchronous buck converters. It shares the same core topology and electrical limits as the IXD3264 but differs in control strategy. The series is designed for applications requiring compact solutions with high efficiency at moderate current levels.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The IXD3264A755MR-G is a functional alternative within the same family, offering similar electrical performance but with added PFM/PWM auto-switching capability. Verify pin compatibility and control loop stability when substituting between these PWM-only and auto-switching variants.
