Wurth Elektronik 178004 Reference Design Board Buck Regulator
MagI³C current source reference design demonstrates how a MagI3C power module can be used for high current LED applications. An adjustable output current limit can be set up to 3A. An output voltage limit can also be set to predefined values which corresponds to end of charge voltages of some common batteries. Batteries can be charged with a dc current or with a defined charging current waveform, if a digital to analogue converter or a PWM output of a microcontroller is used instead of the jumpers for current adjustment. An end of charge voltage can also be set as well as super cap charging. High power LEDs can be supplied up to 3A. During the development of a customer's prototype, the MagI³C current source can be implemented into the prototypes housing until the LED driver or batteries/supercap charger is defined for the ready to market product.
- Current can be adjusted individually by jumper
- Current dynamically adjustable by external microcontroller (using PWM)
- Voltage limit / end of charge voltage can be set by jumper
- Ability to drive 1-4 white high power LEDs
- MagI³C power module 171031801 used as current source
- Conducted and radiated EMI compliant (EN55032)
- Used in constant current source, battery charger, super capacitor charger, high power LED driver
- Input voltage range from 4V to 18V, output voltage range from 0V to 17V
- Output current limit from 0A to 3A, switching frequency is 850KHz, maximum output power of 51W
