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 components 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 compliance with margin • Frequency dithering algorithm allows EMI compliance with margin • Enables fully
