Overview
The ZXLD1320DCATC is a DC-DC buck converter LED driver IC from Diodes Incorporated. It features an integrated power switch and supports input voltages from 4V to 18V. The device delivers a maximum output current of 1.5A with a fixed switching frequency of 1MHz. It utilizes a DFN4030-14 package for surface mount installation. Key electrical parameters include a minimum operating voltage of 4V, a maximum supply voltage of 18V, and PWM dimming capability for brightness control.
Feature Summary
- Integrates a high-side power switch for compact design
- Supports pulse-width modulation (PWM) dimming for precise brightness adjustment
- Operates at a fixed 1MHz switching frequency to minimize external component size
Applications
- General LED lighting applications
- Battery-powered LED drivers
- Low-voltage LED backlighting systems
Procurement Notes
Verify the specific suffix 'CATC' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the target PCB footprint for the DFN4030-14 package. Cross-reference RoHS compliance status with the latest environmental declaration documents provided by Diodes Incorporated before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring up to 1.5A drive current within an 18V input range. The fixed 1MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider thermal dissipation requirements given the 1.5A output capability in the DFN4030-14 package. Verify that the application does not exceed the maximum supply voltage limits during transient conditions.
Part Context
This part belongs to the ZXLD1320 series of LED drivers designed for high-efficiency step-down conversion. It is distinct from higher-voltage variants like the ZXLD1366 or lower-current models such as the ZXLD1352. The series focuses on integrating power switches to reduce board space for portable and general illumination designs.
Replacement Considerations
Direct substitutes may include other ZXLD1320 variants with different suffixes indicating package or temperature variations. Verify pin-to-pin compatibility and electrical parameter equivalence with Diodes Incorporated documentation before substitution.
