SP6879

SP6879 Multi Mode PWM Controller DESCRIPTION The SP6879 is a low cost, multi mode PWM controller intended for flyback topologies. The internal valley detector ensures the converter operates at quasi-resonant operation at high line voltage. IC operates in fixed frequency mode when the line voltage is low. Under certain conditions, SP6879 can be operated in PFM or burst mode. The build-in advanced energy saving function would provide the users a superior AC/DC power application of higher efficiency, and lower standby power. The rich set of protection features such as VCC Under Voltage Lockout (UVLO), VCC Over Voltage Protection (VCC OVP) and clamp, load Over Voltage Protection (OVP), Over Load Protection (OLP), on-chip Over Temperature Protection (OTP), line OVP and programmable Brownout Protection, to realize low component counts and high performance power supply. SP6879 is available in SOP-8 packages.
