Overview
The ZXLD383ET5TA is a single or multi-cell LED driver IC from Diodes Incorporated, designed for step-up voltage conversion from very low input voltages. It operates with a supply voltage range of 900 mV to 3.3 V and delivers an output current of 800 mA. The device utilizes a boost topology with a switching frequency of 330 kHz, supporting output voltages up to 20 V. Packaged in a TSOT-23-3 format, it functions within a temperature range of -20°C to +85°C.
Feature Summary
- Integrated boost converter architecture for efficient step-up voltage regulation
- Capable of driving LEDs from very low input voltage sources
- Supports enable control and rectifier input configurations
Applications
- Single cell battery powered LED lighting systems
- Multi-cell LED driver solutions requiring low input voltage
- Portable electronic devices utilizing boost topology for illumination
Procurement Notes
Verify the specific suffix ET5TA against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the required operating temperature range of -20°C to +85°C for your application environment. Cross-reference the 800 mA output current capability with your LED load requirements before finalizing procurement.
Selection Notes
Select this component when a boost topology is required to drive LEDs from inputs as low as 900 mV. The TSOT-23-3 package suits space-constrained designs. Confirm that the 330 kHz switching frequency aligns with electromagnetic interference constraints. Verify that the 20 V maximum output voltage meets the forward voltage requirements of the target LED string.
Part Context
This part belongs to the ZXLD383 series of LED drivers manufactured by Diodes Incorporated. The series focuses on applications needing step-up conversion from minimal input voltages. The ET5TA designation specifies the surface-mount TSOT-23-3 packaging variant suitable for automated assembly processes.
Replacement Considerations
Consult the official Diodes Incorporated datasheet for verified pin-compatible substitutes within the same family. Do not assume functional equivalence with other boost converters without verifying electrical parameters and package dimensions.
