The Infineon CDM10VD4XTSA1 is a flexible dimming controller in a SOT-23-6 package, designed for LED lighting and similar dimming applications. The 'flexible' label in the description suggests programmable dimming profiles or adjustable output characteristics, so it is not a fixed-frequency PWM generator but a configurable controller that adapts to the load and dimming protocol.
Supply voltage range — 11V to 25V
The 11V to 25V input range covers common LED driver rails from 12V to 24V nominal. On a 12V rail you have 1V of headroom below the minimum; on a 24V rail you are well inside the upper limit. If your design runs a 12V ±10% rail, the 11V floor gives you margin through brownout or cold-crank. At the top end, 25V leaves room for 24V nominal plus a 4% tolerance without hitting the ceiling.
The SOT-23-6 footprint is compact — about 3 mm × 3 mm — so it fits tight PCB layouts in retrofit LED bulbs or linear drivers.
