MT3611A 10.5W 800V AC/DC Primary-Side Feedback Control Chip - SOP-7

MT3611A 10.5W 800V AC/DC Primary-Side Feedback Control Chip - SOP-7

MT3611Ais built-in 800V (Vcbo) power three-pole series high-performance AC/DC low-power edge feedback control chip, using pulse Frequency Modulation (PFM) Built-in non-continuous conduction mode (DCM) of countercurrent power, built-in QR mode. This chip provides accurate constant voltage, constant current (CV) /CC）No optical coupler and secondary adjustment control circuit. Eliminates the need for circuit compensation circuit, while maintaining good stability. Achieves good adjustment and high average efficiency, meets air current loss less than 75mW. There is also an exclusive cable voltage drop compensation function, that is, output line loss compensation.

The line loss compensation amount can be adjusted according to the FB voltage drop resistance resistance value, the maximum compensation amount can be 12% of the output voltage.效 Compensation output current loss of voltage drop on the output line. Main applications of mobile phone, cordless telephone, PDA, MP3 and other portable devices such as adapter battery charger LED Drive current requirement power supply linear power and upgrade replacement of RCC switch power.
