ZXSC400E6TA

Overview

The ZXSC400E6TA is a single-output DC-DC boost converter LED driver manufactured by Diodes Incorporated. It operates within an input voltage range of 1.8V to 8V and delivers a regulated output current of 50mA. The device utilizes a fixed switching frequency of 200kHz and features an internal power switch. Designed for surface-mount installation in SOT-23-6 packages, it supports adjustable output voltage configurations. The component functions reliably across a temperature range of -40°C to +85°C and includes a shutdown function for power management.

Feature Summary

• Integrates an internal power switch to minimize external component count
• Provides constant current regulation for single-channel LED applications
• Includes a dedicated shutdown pin for system power control

Applications

• LED backlighting systems
• Portable electronic device illumination
• Low-power indicator lighting circuits

Procurement Notes

Verify the specific suffix E6TA against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS3 and REACH regulatory requirements before integration. Cross-reference the part number with authorized distributor catalogs to validate authenticity and traceability. Confirm that the ordering information matches the exact electrical characteristics required for the target design.

Selection Notes

Select this component for designs requiring a compact boost topology with integrated switching capabilities. The SOT-23-6 package suits space-constrained PCB layouts. Verify that the 50mA output current aligns with the LED string requirements. Consider the 200kHz switching frequency when designing external inductor and capacitor values to ensure stable operation and minimal electromagnetic interference.

Part Context

This part belongs to the ZXSC400 series of LED drivers from Diodes Incorporated. The series focuses on efficient power management for small form-factor electronics. Similar parts in the family may offer different current ratings or topologies, but share common packaging and interface standards. The ZXSC400E6TA specifically targets low-current LED driving applications requiring high efficiency in a minimal footprint.

Replacement Considerations

Check for direct substitutes within the ZXSC400 series or compatible boost converters from other manufacturers. Ensure pinout compatibility and equivalent electrical parameters such as input voltage range and output current capability. Verify that any replacement maintains the same package style and thermal performance characteristics.
