NCR320ZX
Overview
The NCR320ZX is a linear constant current LED driver from Nexperia designed to provide a stable output of up to 250mA. Housed in a SOT-223 package, it features a maximum supply voltage of 16V and supports PWM dimming for precise brightness control. This AEC-Q101 qualified component is engineered for applications where robust current regulation and thermal performance are critical.
Why Choose This Part
This driver offers a high operating temperature range up to 150 degrees Celsius, making it suitable for high-density or automotive environments. The integrated internal switch simplifies circuit design by reducing external component count compared to discrete transistor solutions.
Applications
Key Specifications
Getting Started
When designing with the NCR320ZX, ensure adequate copper area on the SOT-223 tab to manage heat dissipation at higher current levels. Connect a PWM signal to the enable/dimming pin for brightness control and verify that the voltage drop across the LED string plus the driver overhead does not exceed the 16V maximum rating.
