Beschreibung
- PMP6867, 9V - 32V input to -28V/1.5A negative output buck-boost LED current regulator. Reference design uses the TPS40170 sync buck controller in a buck-boost converter to regulate the current in a series string of 6 to 8 LEDs (-28V) at up to 1.5A. Efficiency is greater than 93%. The output current can be adjusted with an external control voltage
