- Current regulation (CC), 100 mA to 4.9 A. Current set resolution (I_SET): 12-bit, read resolution (I_MON): 15-bit
- PWM LED dimming
- MCU generated two counterphase switching frequencies
- On-board power pre-regulator and bias power supply
- Output Enable (OE) and Constant Current mode (CC) LED indications
- Output LC filter for improved ripple and noise
- On-board 4 mm power output terminals with standard (19.05 mm) pitch
- Pass-thru connector for Vout- coupling with other DIB power modules
- Galvanically isolated SPI bus for communication with MCU board
- I2C EEPROM for storing board specific configuration and calibration parameters
