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
C2173
SOT23-6
• 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 compliant solutions for “MoU” universal USB chargers
o Optimised control of the primary switch drive for low EMI and compliance to EN 301 489-34
o Inherently low ripple and low EMI enable compliance with the interoperability standard, IEC 62684
• Full featured protection includes
o Single fault
o Output over-voltage and short-circuit
o Input under-voltage
• Convenient SOT23-6 surface mount package for small size and low cost manufacture
APPLICATIONS
Universal input mobile phones chargers typically to 8 W, including “universal” USB and all major OEM
specifications.
Universal input adapters and standby/auxiliary power supplies typically to 8 W.
