描述 Description

Power Factor Correction Controller The IN-PLUG IPS101 is a primary-side switching controller which provides high performance active power factor correction (PFC). The PFC circuitry forces the SMPS to draw a current proportional to the instant AC line voltage in order to charge a storage capacitor thus resulting in excellent power factor and low-line harmonics generation. The output of the PFC is a regulated voltage which slightly exceeds the peak line voltage.Features Capable of driving a broad range of power MOSFETs Uses a self-oscillating topology good to 300kHz Voltage error amplifier with provision for loop stability compensation High efficiency over 96% (in optimized designs) Minimum external component count 3-input current-mode multiplier ensures good performance at any line voltage or load Under-voltage protection. Cycle-by-cycle current limiting. Thermal shutdownApplications SMPS Electronic ballast  ROHS, PB Free
