C2173 Datasheet
Primary Side Sensing SMPS Controller
KEY Features
AND ADVANTAGES
- Advanced primary sensing control circuitry achieves accurate voltage and current (CV and CC) regulation
- Bipolar junction transistor (BJT) primary switch enables ultra low BOM cost design solutions
- Fast start-up performance without additional active ponents for low BOM cost
- Adaptive base and emitter switching extends RBSOA
- Less than 30 mW no-load power with less than one second turn-on delay and class leading load-transient performance
- Output transient detection (TD) function for very low no-load power applications
- Optimised PWM/PFM with quasi resonant switching enables efficiency standards...
