IFXCDM10V4XTSA1
Overview
The CDM10V4XTSA1 is a highly integrated 0-10V dimming interface IC designed to bridge the gap between analog dimming signals and PWM-controlled LED drivers. It transforms a 0-10V analog input or a simple resistive dimmer into a 2kHz PWM signal with a fixed 5mA peak output current, facilitating easy dimming integration in space-constrained lighting applications. This device significantly reduces component count by replacing complex discrete circuits with a single SOT-23-6 package.
Why Choose This Part
It features a wide Vcc supply range of 11V to 25V and maintains high accuracy with only 3 percent variation between devices. The IC includes an internal 100uA bias current for resistive dimmers and supports dim-to-off capability, allowing for a simplified PCB layout and reduced bill of materials.
Applications
Key Specifications
Getting Started
To evaluate this IC, design a PCB with the SOT-23-6 footprint ensuring the Vcc supply remains within the 11V to 25V range. Connect the 0-10V control signal to the Dim pin and use the PWM output to drive the dimming input of an offline LED controller or flyback switcher. Refer to the Infineon application notes for recommended external RC filtering to stabilize the 2kHz PWM output in high-noise environments.
