HR1002A is an enhanced LLC controller that provides robust adaptive dead-time adjustment (ADTA) and capacitive mode protection (CMP), as well as improved functional surge performance. ADTA automatically inserts a dead time between the two complimentary gate outputs. This is ensured by keeping the outputs off while sensing the dV/dt current of the half-bridge switching node. ADTA simplifies design and provides lower EMI, as well as higher efficiency. The HR1002A incorporates capacitive mode protection, which prevents potentially destructive capacitive mode switching if the output is shorted or is severely overloaded. This feature protects the MOSFET during abnormal conditions to provide a robust converter. The HR1002A has a configurable oscillator that sets both the maximum and minimum switching frequencies. Applications includes LCD and PDP TVs, desktop PCs and servers, telecom SMPSs, AC/DC adapters, open-frame SMPSs, power tools, video game consoles and electronic lighting ballasts.
