The EEZ DIB DCM224 Power module features dual sync buck converters based on LT3763 with programmable output voltage, PWM dimming and current limit.
- On-board STM32F373 MCU Power input: 48 Vdc (e.g. Mean Well LRS-150F-48)
- Combined max. output power: up to 155 W
- Separate control of each power outputs
- Voltage regulation (CV), 1 – 24 V. Voltage set resolution (U_SET): 12-bit, read resolution (U_MON): 15-bit
- Current regulation (CC), up 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
- Dimensions: 155 x 95 mm, 4-layer PCB
- CE certified design
