Overview
The ZXLD1362ET5TA is a single-channel buck LED driver IC from Diodes Incorporated, designed for high-efficiency lighting applications. It integrates a power switch and high-side current sensing within a compact TSOT-23-5 package. The device operates with an input voltage range of 6 V to 60 V and supports a maximum output current of 1 A. It features a fixed switching frequency of 1 MHz and can drive loads up to 65 V. The component is qualified to AEC-Q100 standards and functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Integrates a power switch and high-side current sense resistor for simplified design
- Supports PWM dimming for precise brightness control
- AEC-Q100 qualified for automotive reliability requirements
Applications
- Automotive interior and exterior LED lighting systems
- General-purpose DC-DC step-down LED drivers
- High-voltage LED string illumination
Procurement Notes
Verify the specific suffix ET5TA corresponds to the TSOT-23-5 surface-mount package and reel/cut-tape availability. Confirm AEC-Q100 qualification status if required for automotive designs. Ensure input voltage specifications align with the 6 V to 60 V operational range. Check for RoHS compliance documentation prior to integration.
Selection Notes
Select this component when a compact solution is needed for driving high-voltage LED strings from a wide input voltage range. The integrated switch eliminates external inductor sizing complexities associated with discrete solutions. Consider the 1 MHz switching frequency for balancing efficiency and passive component size. Verify thermal performance within the TSOT-23-5 package for the intended load current.
Part Context
This part belongs to the ZXLD1362 series of LED drivers from Diodes Incorporated. It is specifically engineered as a continuous mode inductive step-down converter. The series targets applications requiring robust performance in electrically noisy environments, such as automotive electronics, while maintaining a small footprint.
Replacement Considerations
Direct substitutes include other Diodes Incorporated parts within the ZXLD136x family, such as the ZXLD1366, which offers similar functionality but may differ in output current ratings or specific pin configurations. Cross-reference datasheets for exact electrical parameter compatibility before substitution.
