Monolithic Power Systems MP3320B
The MP3320B is an 4-channel, synchronous boost RGBW LED driver that operates across a wide 2V to 5.5V input voltage voltage (VIN) range. Each channel can reach a maximum current of up to 102mA and a maximum output voltage (VOUT) of up to 5.4V. The MP3320B integrates an I2C interface with up to 16 configurable I2C addresses via an external resistor.| Part No. | MP3320B |

DESCRIPTION
Each channel can be enabled or disabled via the I2C. The MP3320B employs both separated pulsewidth modulation (PWM) dimming and analog dimming for each LED channel, as well as 10bit PWM dimming and 8-bit analog dimming for each channel. Phase shift is also integrated during PWM dimming to reduce inrush current and eliminate audible noise. To ensure system reliability, the MP3320B integrates rich protections, including LED open protection, LED short protection, over-voltage protection (OVP) and over-temperature protection. The MP3320B is available in a QFN-14 (2mmx2mm) package. MP3320B 4-Channel, Synchronous Boost RGBW LED Driver with I2C InterfaceFEATURES
