The startup resistor is typically connected to AC line for a fast reset of latch protection 4 AC Line RET FAN6863 Figure 24 Startup Circuit Green Mode Operation The FAN6863 uses feedback voltage Vrs as an indicator of the output load and modulates the PWM frequency as shown in Figure 25 such that the switching frequency decreases as load decreases In heavy load conditions the switching frequency is 65kHz Once Vrs decreases below Vrsg n 2 5V the PWM frequency starts to linearly decrease from 65kHz to 22 5kHz to reduce the switching losses As Vra decreases below Vre c 2 2V the switching frequency is fixed at 22 5kKHz and FAN6863 enters deep Green Mode where the operating current decreases to 600uA maximum further reducing the standby power consumption As Veg decreases below Vrgzpc 1 6V FAN6863 enters Burst Mode operation When Vrs drops below Vrgzpc Switching stops and the output voltage starts to drop which causes the feedback voltage to rise Once Veg rises above Vrgzpc switching resumes Burst Mode alternately enables and disables switching thereby reducing switching loss in Standby Mode as shown in Figure 26 2011 Fairchild Semiconductor Corporation FAN6863 Rev 1 0 1 Frequency PWM Frequency Vrg N Vra Vra zpc VeB c Figure 25 PWM Frequency a j Switching Disabled Hd He Switching Disabled Figure 26 Burst Mode Operation Frequency Hopping
7. EMI reduction is accomplished by frequency hopping which spreads the energy over a wider frequency range than the bandwidth measured by the EMI test equipment An internal frequency hopping circuit changes the switching frequency between 60 8kHz and 69 2kHz with a period of 4 4ms as shown in Figure 27 f S 69 2kHz 65 0kHz 60 8kHz 4 4ms i Figure 27 Frequency Hopping 49j041u02 INMd 9poIy ue9145 pejeJ6e1u AjuDiH 989NV 4 www fairchildsemi com Protections Self protective functions include Vpp Over Voltage Protection OVP Open Loop Overload Protection OLP Over Current Protection OCP Short Circuit Protection SCP SENSE pin Short Circuit Protection SSCP and Over Temperature Protection OTP OLP OCP SCP and SSCP are auto restart mode protections OVP and OTP are latch mode protections Auto Restart Mode Protection Once a fault condition is detected switching is terminated and the MOSFET remains off This causes Vpp to fall because no more power is delivered from auxiliary winding When Vpp falls to Vpp orr 7V the protection is reset and the operating current reduces to startup current which causes Vpp to rise FAN6863 resumes normal operation when Vpp reaches Vpp oN 16V In this manner the auto restart can alternately enable and disable the switching of the MOSFET until the fault condition is eliminated see Figure 268 M Triggers Fault Removed i r m Operating Current
