MT3688

MT3688A  12W, MT3688B  15W, MT3688C  18W;

    MT3688 is a high performance Primary Side Regulation (PSR) controller with high precision CV/CC control ideal for charger applications. In CV mode, MT3688 adopts Multi Mode Control which uses the hybrid of AM (Amplitude Modulation) mode and FM (Frequency Modulation) mode to improve system efficiency and reliability.
   In CC mode, the IC uses PFM control with line and load CC compensation. The IC can achieve audio noise free operation and optimized dynamic response. The built-in Cable Drop Compensation (CDC) function can provide excellent CV performance.
   MT3688 integrates functions and protections of Under Voltage Lockout (UVLO), VDD over Voltage Protection (VDD OVP), Cycle-by-cycle Current Limiting (OCP), Short Load Protection (SLP), Gate Clamping, and VDD Clamping.
