Produk ASLI dari Powerlink Microelectronics Inc. Mfr.Part #: PL3368C Key Features - Built-in Integrated Power BJT - Accurate Constant Current Regulation at Universal AC input - Eliminates Opto-coupler and all Secondary CC/CV Control Circuitry - Built-in Line Compensation for Tighter CC/CV Regulation - Built-in Compensation for Transformer Inductance Tolerances - Adjustable Output Cable Compensation - Adaptive Multi-mode PFM Control for Improving Efficiency - Low Start-up Current - Built-in Leading Edge Blanking (LEB) - Cycle-by-Cycle Current Limiting - VDD Under Voltage Lockout and VDD over voltage protection - Built-in Short Circuit Protection and Output Overvoltage Protection - Over temperature protection Product Description PL3368C(x) is a series of high efficiency Primary Side Regulator and highly integrated PWM Power Switch for AC/DC power supply applications. It simplifies conventional CC/CV charger/adaptor designs by eliminating the opto-coupler and secondary control circuitry. Constant output voltage and current regulation is realized as shown in the Fig.1 below. Multi-mode operations are utilized to achieve low standby power, high efficiency and audio amp; noise free. PL3368C operates in PFM mode at large load condition, with the load becomes medium or light, the chip operates in Green mode to achieve high efficiency. PL3368C also offers rich protection features including Cycle-by-Cycle peak current limiting, UVLO, OTP, load OVP, and VDD over voltage.
