ZXSC410E6TA

Overview

The ZXSC410E6TA is a voltage mode boost switching controller manufactured by Diodes Incorporated, designed for step-up DC-DC conversion applications. It operates within an input supply voltage range of 1.8V to 8V and features a fixed switching frequency of 200kHz with a maximum duty cycle of 85%. The device utilizes a single-channel output configured as a transistor driver for positive output regulation. Packaged in a compact SOT-23-6 surface-mount format, it supports operation across a temperature range of -40°C to +85°C. Key control characteristics include an enable function, while the component does not incorporate synchronous rectification or clock synchronization capabilities.

Feature Summary

• Integrates a voltage mode boost converter topology for efficient step-up power management
• Includes an enable pin for precise system power state control and shutdown functionality
• Features a fixed 200kHz switching frequency to optimize external component size and efficiency

Applications

• General purpose boost converter circuits
• Battery-powered portable electronics
• LED driver pre-regulation stages

Procurement Notes

Verify the specific suffix E6TA against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure that the required operating temperature range aligns with the -40°C to +85°C industrial rating. Confirm that the application circuit design accommodates the 200kHz switching frequency and the 85% maximum duty cycle limitations defined in the official electrical characteristics.

Selection Notes

Select this component when a non-synchronous boost controller is required for cost-sensitive designs. The 1.8V minimum input voltage allows compatibility with single-cell lithium-ion batteries. The SOT-23-6 package provides a small footprint suitable for space-constrained mobile devices. Designers must account for the absence of synchronous rectification, which impacts efficiency at higher load currents compared to synchronous alternatives.

Part Context

This part belongs to the ZXSC410 series of DC-DC boost switching controllers from Diodes Incorporated. It shares functional similarities with other members like the ZXSC420 and ZXSC440, primarily differing in specific internal reference voltages and protection thresholds. The E6TA suffix denotes the standard commercial grade packaging configuration used for high-volume manufacturing integration.

Replacement Considerations

Direct substitutes within the same family include ZXSC420E6TA and ZXSC440E6TA. Verify that the alternative part number matches the required output voltage regulation and current drive capabilities before implementation.
