Typical Applications
CDM10VXTSA1 is suitable for 6 applications: 0-10V Dimmable LED Downlights, Architectural and Theatrical Dimming, Fluorescent-to-LED Retrofit Lamps, Smart Lighting with Wireless Module, DALI-to-0-10V Translation Boards, Emergency Lighting with Dim Control.
0-10V Dimmable LED Downlights
The CDM10VXTSA1 is purpose-built for 0-10V dimmable LED downlights operating from 12 V to 24 V constant-voltage LED driver rails. Its 11-25 V supply range matches the standard commercial-lighting bus voltages (12V, 15V, 18V, 24V) and its integrated 5 V LDO can bias an external wireless MCU module without adding a regulator. With ~3 mA quiescent current and 6-pin SOT-23-6 footprint, the part fits into the small driver cavity of a 4-inch downlight. Connected between the wall dimmer's 0-10V control lines and the LED driver's PWM input, it provides smooth 1-100% dimming with no flicker. Use 100 nF X7R bypass on VCC and a 10 kΩ pull-up on the open-drain DIM output.
Recommended
Architectural and Theatrical Dimming
In architectural and theatrical lighting installations, the CDM10VXTSA1 interfaces legacy 0-10V wall stations and DMX-to-0-10V gateways to modern constant-current LED fixtures. Its wide 11-25 V supply tolerance handles long cable runs with significant IR drop on the dimming bus, a common issue in large venues. The integrated 5V LDO can power a small MCU for fixture-addressable dimming. The open-drain DIM output can be paralleled with multiple driver ICs without conflict. Operating temperature range of -40°C to +125°C supports outdoor stage and facade fixtures when paired with a conformal-coated driver PCB.
Recommended
Fluorescent-to-LED Retrofit Lamps
The CDM10VXTSA1 is a compact solution for T8/T5 fluorescent-to-LED retrofit tubes and troffers where existing 0-10V dimming infrastructure must be preserved. Its 6-pin SOT-23-6 footprint fits inside the limited end-cap space of a linear LED tube, and its integrated 5V LDO can power an optional occupancy sensor MCU. The device tolerates the 24 VDC auxiliary rail typical in retrofit fixtures and provides clean PWM dimming without audible flicker. Use the dimmer's existing 0-10V pair directly, with a 100 nF bypass cap on VCC and a 1 kΩ pull-up on the DIM output.
Recommended
Smart Lighting with Wireless Module
In wireless smart-lighting fixtures (Zigbee, Bluetooth Mesh, Matter), the CDM10VXTSA1 acts as the bridge between a 0-10V gateway and the LED driver. The integrated 5 V LDO powers the wireless SoC module directly, eliminating a separate regulator and saving PCB area. The 0-10V dim input remains the control interface, while the wireless MCU converts Zigbee/Matter dim commands into 0-10V. With approximately 3 mA quiescent current, total standby is acceptable for battery-backed emergency lighting. Operating from 11-25 V supports both 12V and 24V LED driver designs in a single SKU.
Recommended
DALI-to-0-10V Translation Boards
DALI-to-0-10V translation boards pair a DALI controller IC with the CDM10VXTSA1 to interface older 0-10V fixtures on a DALI bus. The CDM10VXTSA1 receives a 0-10V analog reference from the translation board's DAC and produces the PWM output for the existing 0-10V LED driver. Its 11-25 V supply range matches 24V auxiliary rails common in DALI bus-powered fixtures. The integrated 5V LDO can power the translation MCU. Designers should add ESD protection on the 0-10V lines since they are exposed to installer wiring transients.
Recommended
Emergency Lighting with Dim Control
In emergency luminaires with dim capability, the CDM10VXTSA1 provides 0-10V dimming on the AC-mains-derived 12V or 24V battery rail while the fixture operates in normal mode. Its 11-25 V supply range covers the float voltage of a 24V SLA battery backup. The integrated 5V LDO powers a small MCU monitoring mains/battery state. Approximately 3 mA quiescent current is acceptable for always-on emergency operation. The -40°C to +125°C operating range supports outdoor cold-weather emergency fixtures.

Key Differentiators
- Wide 11-25 V supply range covering all standard LED lighting bus voltages (vs CDM10VD)
- Integrated 5 V LDO for external MCU bias (vs Discrete 0-10V dim circuits)
- Compact 6-pin SOT-23-6 footprint for space-constrained fixtures (vs Larger 0-10V controller ICs in SOIC-8 or QFN packages)
Design Notes
Estimated: At VCC=24 V and 3 mA quiescent current, the CDM10VXTSA1 dissipates approximately 72 mW internally. The 5V LDO can deliver up to several mA to an external MCU; budget total VCC current accordingly. Add a 100 nF X7R ceramic bypass capacitor directly at the VCC pin (within 2 mm) and a 1 µF bulk capacitor for line-transient robustness. The IC's wide 11-25 V supply range means designers do not need a pre-regulator on 24V industrial lighting buses, but a TVS diode (e.g., 26V SMAJ) is recommended if the bus is exposed to installer wiring surges.
Do not connect the DIM pin (pin 2) to a low-impedance voltage source - the CDM10VXTSA1 is a current sink, not a voltage input, and the dimmer wall controller must source the 0-10V signal. Connecting DIM directly to a bench power supply will saturate the input stage. The PWM_OUT pin (pin 4) is open-drain and requires an external pull-up resistor to the downstream LED driver's reference rail (typically 3.3V or 5V); omitting this resistor results in no PWM signal at the driver. The NC pin (pin 6) should be left floating per the datasheet.
Use a 4-layer PCB with a solid ground plane under the IC to provide thermal spreading and EMI shielding for the analog DIM input. Keep the high-current LED driver traces (if integrated nearby) at least 5 mm from the DIM input trace to avoid noise coupling that can cause flicker at low dim levels. Place the VCC bypass capacitor and 5V LDO output capacitor as close to their respective pins as possible. The exposed pad of the SOT-23-6 package is not present on the CDM10VXTSA1; thermal performance is sufficient for the ~3 mA quiescent load without copper pours.
