Overview
The ZXLD1356DACTC is a single-channel LED lighting driver IC manufactured by Diodes Incorporated. It utilizes a buck topology to regulate current for high-power LEDs. The device supports an input voltage range of 6 V to 60 V and delivers a maximum output current of 550 mA. It operates at a switching frequency of 500 kHz and features integrated PWM dimming capabilities. The component is housed in a DFN-6 (V-DFN3030-6) surface-mount package. It includes open LED protection and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Integrates a power switch and control circuitry for efficient step-down LED regulation
- Supports pulse-width modulation dimming for precise brightness control
- Includes built-in open LED protection to enhance system reliability
Applications
- General solid-state lighting fixtures
- Automotive interior illumination systems
- Portable battery-powered LED lamps
Procurement Notes
Verify the specific ordering suffix 'DACTC' against the manufacturer's official datasheet to confirm the exact reel quantity and tape-and-reel specifications. Ensure that the procurement channel provides valid traceability documentation. Confirm that the received components match the specified DFN-6 package dimensions and pinout configuration prior to integration into the design.
Selection Notes
Select this component when designing circuits requiring a compact, single-channel solution with a wide input voltage range up to 60 V. It is suitable for applications demanding integrated switching capability and PWM dimming functionality without external discrete switches. Consider the thermal performance of the DFN-6 package relative to the expected power dissipation levels in the target application environment.
Part Context
This part belongs to the ZXLD1356 series of LED drivers from Diodes Incorporated. The series is designed for high-efficiency, low-component-count LED lighting applications. The ZXLD1356DACTC variant specifically denotes the DFN-6 packaged version intended for surface-mount assembly processes, distinguishing it from other package options within the same functional family.
Replacement Considerations
The ZXLD1356QET5TA is a documented alternative within the same product family, offering identical electrical functionality but utilizing a TSOT25-6 package instead of the DFN-6 form factor.
