Voltage Regulators - DC DC Switching Regulators datasheet and documents for IXD3263A755MR-G

IXD3263A755MR-G

Voltage Regulators - DC DC Switching Regulators Overview

The IXD3263A755MR-G is a synchronous step-down DC-DC converter manufactured by Zilog. It operates with an input voltage range of 3V to 18V and provides a positive adjustable output from 1V to 15V. The device delivers a maximum output current of 500mA and switches at a frequency of 500kHz. It features PFM/PWM auto-switching for efficiency optimization across load conditions. The component is housed in a SC-74A (SOT-753) surface-mount package and supports an operating temperature range of -40°C to 105°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Synchronous rectification topology for improved power conversion efficiency
Automatic switching between Pulse Frequency Modulation (PFM) and Pulse Width Modulation (PWM) modes based on load demand
Adjustable output voltage capability within specified limits

Voltage Regulators - DC DC Switching Regulators Applications

Battery-powered portable electronic devices requiring efficient power management
Embedded systems utilizing microcontrollers or digital signal processors
Industrial control modules operating within wide input voltage ranges

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '5' against official Zilog documentation to confirm pinout and functional compatibility, as variations exist within the series. Confirm RoHS compliance status through the manufacturer's latest environmental declarations. Ensure the SC-74A footprint matches the target PCB design constraints before finalizing procurement decisions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an input voltage up to 18V must be regulated down to a lower adjustable level with moderate current requirements. The integrated synchronous rectifiers make it suitable for applications prioritizing thermal performance and efficiency over cost-sensitive non-synchronous alternatives. Evaluate the 500kHz switching frequency against electromagnetic interference (EMI) constraints in the target system design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the IXD32xx series of switching voltage regulators designed for general-purpose power management. It serves as a compact solution for converting higher battery or rail voltages to stable logic levels. The SOT-753 package allows for space-constrained designs common in modern consumer electronics and industrial instrumentation.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The XC9263A75DMR-G from Torex Semiconductor Ltd is documented as a parameter-equivalent alternative. Verify pin-to-pin compatibility and electrical specifications against the original datasheet before substitution.
