SP6879

Quasi-Resonant PWM Controller

DESCRIPTION

APPLICATIONS

The SP6879 is a low cost, Quasi-Resonant (QR)

PWM controller intended for flyback topologies. The

internal valley detector ensures the converter operates

at quasi-resonant operation over wide range of line

voltage. IC operates in fixed frequency mode for

some particular conditions . The build-in advanced

energy saving function would provide the users a

superior AC/DC power application of higher

efficiency, and lower cost solution for applications.

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) and

on-chip Over Temperature Protection (OTP), Brown

Out/In helps to realize low component counts and

high performance power supply.

SP6879 is available in SOP-8/ DIP-8P packages.
