The LP3943ISQX/NOPB from Texas Instruments is an integrated circuit designed to independently drive 16 LEDs, suitable for applications such as camera flash. This device operates with an input voltage range of 2.3V to 5.5V and provides up to 25mA of current per channel.
Control is managed through I2C or SMBus interfaces, allowing for versatile dimming capabilities. The device features an internal precision oscillator for timing and includes two prescaler registers and two PWM registers for duty-cycle control. It operates within a temperature range of -40°C to 85°C.
The LP3943ISQX/NOPB is available in a 24-WQFN (4x4) surface-mount package. It features internal switches and offers a shutdown current of 2µA typical and a quiescent current of 0.35mA typical.
