IXD3265C181MR-G

Voltage Regulators - DC DC Switching Regulators Overview

The IXD3265C181MR-G is a synchronous step-down DC-DC converter manufactured by Zilog. It operates as an ultra-low power switching voltage regulator with a fixed output voltage of 1.8 V and a maximum output current of 200 mA. The device features a PFM control topology and supports an input voltage range from 2 V to 6 V. Quiescent current is specified at 0.5 uA, ensuring minimal power consumption during standby or light-load conditions. The component includes auto-discharge functionality for the output capacitor.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Synchronous step-down architecture for efficient power conversion
• Ultra-low quiescent current operation for extended battery life
• Integrated auto-discharge circuitry for output safety

Voltage Regulators - DC DC Switching Regulators Applications

• Battery-powered portable electronic devices
• Low-power embedded systems requiring stable 1.8 V rails
• Wearable technology with strict power constraints

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific manufacturer designation, as Zilog's semiconductor assets were acquired by Microchip Technology. Confirm that the IXD3265 series documentation aligns with current Microchip product lines. Ensure the package type matches the required PCB footprint and check for any RoHS compliance certifications relevant to the manufacturing date code.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8 V output is required with minimal static power draw. The 200 mA current limit suits low-power microcontrollers and sensors. Consider the 2 V to 6 V input range compatibility with single-cell lithium batteries or regulated supplies. The synchronous design offers better efficiency than non-synchronous alternatives at moderate loads.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the IXD3265 family of ultra-low power DC-DC converters. Similar variants in the series include different fixed output voltages, such as the IXD3265C251MR-G (2.5 V) and IXD3265C301MR-G (3.0 V). All share the same core architecture, pinout, and low-power characteristics, differing primarily in the internal feedback resistor network setting the output voltage.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes within the same family include IXD3265C251MR-G and IXD3265C301MR-G if the output voltage requirement differs. For cross-manufacturer replacements, verify pin compatibility and electrical specifications against similar ultra-low power buck converters.
