Power Management IC
Power Factor Corrector (PFC)
The IC provides high power factor, low total harmonic distortion and stabilized output voltage. The IC is designed to operate in the continuous current mode of step-up converters with control of the input current in the voltage range of 85… 264V. The switching frequency can be programmed to anywhere between 48kHz to 200kHz based on the specific application requirement. In addition, the IC offers several advanced system-enabling and protective features such as dedicated pin for overvoltage protection, cycle by cycle peak current limitation, open loop protection, voltage lockout protection, soft-start and micropower startup/sleep-mode with IC current consumption less than 200μA.
