PT2312E CC/CV Primary-Side Green Mode Convertor
■ The PT2312E is a high performance AC/DC power convertor for charger and adaptor applications. Due to the PSR control, the PT2312E can provide accurate constant voltage (CV) and constant current (CC) regulation without opto-coupler and TL431.
■ The PT2312E adopts PFM method in CC control mode and PFM/PWM method in CV control mode. In order to achieve high performance, The PT2312E uses quasi-resonant (QR) switching to improve the efficiency, frequency shuffling technique to optimize EMI design and built-in cable drop compensation to meet good load regulation.
■ The PT2312E utilizes soft start control and multi-protection to meet high reliability, such as cycle-by-cycle current limiting, output OVP, VCC OVP/UVLO, sense resistor open/short protection, OTP etc.
■ PT2312E is offered in SOP-7 package.
