[Supply] LP5030RJVR (TI) 12-Bit PWM Ultra-low Quiescent Current I2C RGB LED Drivers

Shenzhen Mingjiada Electronics Co., Ltd.——Long-term supply of TI (LP5030RJVR) 30-channel I2C constant-current RGB LED driver, which uses 12-bit PWM resolution and 29 kHz switching frequency to control each LED output. This control helps to obtain a smooth drop in intensity and eliminates audible noise.

Product Details:

The LP5030RJVR is a 30-channel constant current trap LED driver.With a 29 kHz, 12-bit PWM generator for each channel, and channel/module independent colour mixing and intensity control (previously known as a luminance control register), the LP5030RJVR is capable of achieving vivid LED effects with zero audible noise.

Model No.: LP5030RJVR

Package: VQFN-46

Type: Constant Current RGB LED Driver

LP5030RJVR Product Features:

Operating Voltage Range:

- VCC Range: 2.7V to 5.5V

- EN, SDA, and SCL pins compatible with 1.8V, 3.3V, and 5V supply rails

- Maximum output voltage: 6V

36 high-precision constant-current traps

- 25.5mA maximum current per channel over the full VCC range

- Maximum current per channel is 35mA at VCC ≥ 3.3V

- Inter-device error of ±5%; inter-channel error of ±5%

Ultra-low quiescent current:

- Shutdown mode: 1µA (maximum) with EN low

- Power Save Mode: 12µA (max), EN high, all LEDs off >30ms

Each channel has an integrated 12-bit 29kHz PWM generator:

- Each channel has an independent colour mixing register

- One independent brightness control register per RGB LED module

- Optional logarithmic or linear scale brightness control

- Integrated three-phase phase shift PWM scheme

3 programmable groups (R, G, B) for easy software control of each colour

2 external hardware address pins allow connection of up to 4 devices

Broadcast slave address allows simultaneous configuration of multiple devices

Auto-Increment allows multiple consecutive registers to be written or read during a single transfer

Fast-mode I2C speeds up to 400kHz
