CDM10VXTSA1 Visão geral
A dimming controller PMIC is a specialized power management integrated circuit that bridges an analog lighting-control protocol (such as 0-10V, DALI, or PWM) and the digital/PWM input of an LED driver stage. In the broader component taxonomy, the CDM10V belongs to the PMIC family, which sits under power management ICs, then under the larger category of signal-chain and power semiconductors. Its primary role is to absorb the analog control voltage and isolate the sensitive control circuitry from the high-current LED driver.
Key features of the CDM10VXTSA1 include integrated 0-10V current sink (typ. 100-200 µA sourcing for 10V input), built-in 5V LDO output for powering external microcontrollers, low quiescent current draw (~3 mA), wide 11V-25V supply range, and active-low PWM output with up to 1 mA drive. The integrated LDO eliminates the need for an external regulator in many designs, reducing BOM count and PCB area. The device is qualified to industrial temperature ranges of -40 °C to +125 °C.
The CDM10VXTSA1 uses a bipolar-CMOS-DMOS mixed-signal architecture that combines low-voltage analog control blocks, a bandgap reference, an integrated pass transistor for the 5V LDO, and DMOS output stages for the dim line and PWM dim output. This co-integration enables very few external components - typically just bypass capacitors and the 0-10V input resistor divider - while still delivering robust line-transient immunity on industrial lighting bus voltages.
Typical applications include 0-10V dimmable LED downlights and troffers, commercial fluorescent-to-LED retrofit lamps, architectural and theatrical dimming systems, emergency lighting with dim control, and smart lighting fixtures that pair the CDM10V with a wireless module receiving commands from a 0-10V gateway. The IC is also used in DALI-to-0-10V translation boards.
When designing with the CDM10VXTSA1, ensure the supply rail stays within 11V-25V and provide a 100 nF ceramic bypass capacitor close to the VCC pin. The 0-10V dim input is current-sinking, so the dimmer wall controller must source the 0-10V signal - do not connect the dim input directly to a low-impedance voltage source. The DIM output is open-drain and requires a pull-up resistor to the driver's reference rail.

Aplicações típicas
CDM10VXTSA1 é adequado para 6 aplicaçãos: 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.
Recomendado
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.
Recomendado
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.
Recomendado
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.
Recomendado
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.
Recomendado
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.

- Integrated 5 V LDO for external MCU bias (vs Discrete 0-10V dim circuits)

Notas de projeto
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.
