一.产品概述  

    JTMB8830A is a high performance, highly integrated QR (Quasi Resonant Mode) and Primary Side

Regulation (PSR) controller for offline small power converter applications.

        JTMB8830A has proprietary QR/PSR control for high efficiency and low EMI. The IC can meet EPS Level

6 energy standard easily. The IC can support “No-snubber & No-Y” design in 5W charger applications. The IC 

also has built-in cable drop compensation function, which can provide excellent CV performance.

       JTMB8830A integrates functions and protections of Under Voltage Lockout (UVLO), VDD Over Voltage

Protection (VDD OVP), Output Over Voltage Protection (Output OVP), Soft Start, Cycle-by-cycle Current Limiting 

(OCP), Pin Floating Protection,Gate Clamping, VDD Clamping.

       JTMB8830A is available in SOT23-6 package.
