Product details
Overview
LP5030RJVR from Texas Instruments is a 30-channel, 12-bit PWM constant-current RGB LED driver IC with ultra-low quiescent current (12 µA in power-save mode), 29-kHz switching frequency to eliminate audible noise, and I²C interface supporting up to 400 kHz. It delivers precise per-channel current control (±5% device-to-device and channel-to-channel error) for synchronized breathing, blinking, and chasing effects in human-machine interface lighting.
For engineers reviewing the LP5030RJVR datasheet, LP5030RJVR pinout, LP5030RJVR application, or LP5030RJVR equivalent, this page provides verified technical context on its 30-channel sink architecture, VQFN-46 package with thermal pad, RGB bank-based software control, and suitability for battery-sensitive smart home and IoT indicator systems.
Technical Context
The LP5030RJVR integrates a 15-MHz internal oscillator, three programmable R/G/B banks for global color-effect control, and hardware address pins (ADDR0/ADDR1) enabling up to four devices on one I²C bus. Its 12-bit PWM generator per channel combines independent 8-bit color-mixing and 8-bit brightness registers - with selectable logarithmic or linear dimming scaling - to achieve >16M color combinations without distortion.
It implements a 3-phase PWM phase-shifting scheme across its 30 outputs to reduce peak input current and ceramic capacitor ringing. The device enters automatic power-save mode (<12 µA) after all LEDs remain off for ≥30 ms, and supports shutdown mode at ≤1 µA via EN pin assertion.
Key Specifications

| PWM Resolution & Freq | 12-bit effective resolution (9-bit PWM + 3-bit dithering) at 29 kHz - ensures smooth dimming and eliminates audible noise. |
| I²C Speed | Up to 400 kHz Fast-Mode - enables rapid register writes for real-time animation updates without MCU overhead. |
| Quiescent Current | 12 µA max in power-save mode (all LEDs off ≥30 ms); 1 µA max in shutdown - critical for battery-powered smart locks and smoke detectors. |
| Current Accuracy | ±5% device-to-device and ±5% channel-to-channel error - guarantees uniform LED intensity across multi-device arrays. |
| Output Voltage Max | 6 V - supports common red/green/blue LED forward voltages with margin for series configurations. |
Pinout & Package
LP5030RJVR uses a 46-pin VQFN package (6.00 mm × 5.00 mm) with exposed thermal pad connected to GND for enhanced thermal dissipation in compact LED modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT0–OUT29 | Constant-current sink outputs | 30 dedicated channels driving RGB LED cathodes; each configurable independently for color and brightness. |
| EN | Active-high chip enable | Hardware master control: pulls low to enter 1-µA shutdown; high enables I²C operation and auto power-save mode. |

| ADDR0 / ADDR1 | Hardware slave address inputs | Set I²C address to select one of four unique addresses (0x60–0x63), enabling daisy-chained multi-driver configurations. |
| IREF | Global current reference input | Connects external resistor to set maximum per-channel current; determines full-scale output accuracy and linearity. |
| VCAP | Internal LDO output filter | Requires 1-µF capacitor to GND; stabilizes internal analog rail for consistent PWM timing and current regulation. |
| GND (Pins 37, 46 + Thermal Pad) | Power and signal ground | Three GND connections including exposed thermal pad - mandatory for thermal performance and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Independent color-mixing & brightness registers | Enables >16 million colors per RGB module while decoupling hue selection from intensity - prevents color shift during dimming. |
| 3-phase PWM phase-shifting | Reduces peak input current by staggering LED turn-on across three temporal groups - lowers required input capacitance and suppresses ceramic capacitor ringing. |
| Auto power-save mode | Enters <12 µA state automatically after 30 ms of zero LED activity - extends battery life in always-on smart home sensors without firmware intervention. |
| Broadcast I²C address | Allows simultaneous configuration of multiple LP5030RJVR devices using 0x6E address - simplifies initialization and animation synchronization across large LED arrays. |
| Logarithmic or linear dimming scale | Configurable via Log_Scale_EN bit - provides perceptually uniform dimming (log) or precise linear control (linear) for calibration-critical applications. |

Use Value: Integrated thermal shutdown (160°C) protects against overheating in enclosed plastic enclosures during prolonged alarm activation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar RGB LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LP5036RJVR | 36-channel version with identical pinout, specs, and feature set; differs only in number of active OUTx pins (36 vs 30). | Used where higher LED count is required (e.g., larger smart display bezels); same PCB layout but requires firmware mapping adjustment. | Select LP5036RJVR if >30 channels needed; LP5030RJVR saves cost and routing complexity for 30-channel designs. |
| TLC59731RTET | 12-channel, 16-bit PWM, SPI interface, no auto power-save mode; max 25 mA/channel; no RGB bank grouping. | Suitable for smaller LED arrays with SPI-capable MCUs; lacks phase-shifting and logarithmic dimming; higher per-channel resolution but lower channel count. | Choose TLC59731RTET for SPI-based systems needing finer grayscale control on ≤12 LEDs; LP5030RJVR preferred for I²C scalability and ultra-low-power HMI. |
Compared with LP5036RJVR, LP5030RJVR offers identical functionality in a 30-channel footprint - reducing BOM cost and layout area without sacrificing features.

FAQ
What is the maximum number of LP5030RJVR devices that can share one I²C bus?
Four LP5030RJVR devices can operate on a single I²C bus using the two hardware address pins (ADDR0 and ADDR1), which configure unique slave addresses (0x60–0x63). This allows scalable LED array expansion without additional GPIOs or bus multiplexers - ideal for multi-zone smart home panels where each LP5030RJVR controls a localized LED group.
Does LP5030RJVR support logarithmic dimming for perceptually uniform brightness steps?
Yes, LP5030RJVR supports both logarithmic and linear dimming scales via the Log_Scale_EN register bit. When enabled, it applies a perceptually uniform curve to the 8-bit brightness register - critical for avoiding visible "jumpiness" during slow fade effects in smart speaker rings or smoke detector indicators. The independent color-mixing register prevents hue distortion during log-scaled dimming.
How does LP5030RJVR reduce input current ripple in LED systems?
LP5030RJVR implements a 3-phase PWM phase-shifting scheme across its 30 outputs: OUT0/OUT3/OUT6… use Phase 1, OUT1/OUT4/OUT7… use Phase 2, and OUT2/OUT5/OUT8… use Phase 3. This staggers LED turn-on timing, lowering peak input current by ~33% and minimizing ceramic capacitor audible ringing - especially valuable in compact, unshielded smart home enclosures.
What is the role of the VCAP pin on LP5030RJVR, and what capacitor value is required?
The VCAP pin on LP5030RJVR connects to the output of an internal LDO regulating the analog core. A 1-µF ceramic capacitor must be placed between VCAP and GND to stabilize this rail - ensuring accurate PWM timing, consistent current regulation, and immunity to supply noise. Omitting or undersizing this capacitor causes brightness instability and increased channel-to-channel error.
Can LP5030RJVR drive LEDs with forward voltages above 5.5 V?
No, LP5030RJVR's absolute maximum output voltage is 6 V, and recommended operating condition for OUTx pins is 0–5.5 V. Driving LEDs with combined forward voltage exceeding 5.5 V risks violating specifications and may cause premature saturation or thermal stress. For higher-Vf LEDs, use external high-side switches or boost converters upstream of LP5030RJVR's current sinks.
