C6182 Datasheet
Primary Sensing SMPS Regulator for Offline Applications
KEY FEATURES AND ADVANTAGES
• Advanced primary sensing control circuitry achieves accurate voltage and
current (CV and CC) regulation without an opto-coupler
• Integrated primary switch and start-up device support application designs with
very low component count
SOP-8
• Advanced insulated gate bipolar transistor (IGBT) technology provides a primary switch that is robust,
reliable and avalanche-capable
• Integrated start-up switch enables very fast turn-on with no impact on no-load power
• Optimised PWM/PFM with quasi-resonant switching enables efficiency standards compliance with margin
• Enables fully compliant solutions for “MoU” Common External Power Supply universal USB chargers
o Switching frequency dither and edge rate control of the primary switch gate drive ease design for
low EMI and compliance to EN 301 489-34 with margin
o Inherently low ripple and low EMI enable compliance with the interoperability standard, IEC 62684
• Best in class load-transient performance and no-load power less than 30 mW for five-star chargers
• Full featured protection includes
o Single fault and over-temperature
o Output over-voltage and short-circuit
o Input under-voltage
• Convenient surface mount SOP-8 package for small size and low cost manufacture
APPLICATIONS
Universal input chargers for mobile phones, including “universal” USB and all major OEM specifications
Universal standby and auxiliary power supplies up to 3.5 W.

Figure 3: Typical Universal Input, Five Star USB Charger Using C6182
By sensing the primary-side
waveforms of transformer voltage and
primary current, the C6182 achieves
constant voltage and constant current
output within tight limits without the
need for any secondary-side sensing
components. Figure 4 shows the
output characteristics of a typical
charger implementation.
