HR1001L Enhanced LLC Controller with Adaptive Dead-Time Control DESCRIPTION FEATURES The HR1001L is an enhanced LLC controller Two-Level Over-Current Protection (OCP): that provides new, adaptive, dead-time Frequency Shift and Latch-Off Mode adjustment (ADTA) and capacitive mode Adaptive Dead-Time Adjustment (ADTA) protection (CMP) features. The HR1001L is the Capacitive Mode Protection (CMP) OCP latch-off version of the HR1001B. 50% Duty Cycle, Variable Frequency Control for Resonant Half-Bridge Converter ADTA inserts a dead time between the two 600V High-Side Gate Driver with Integrated complimentary gate outputs automatically by Bootstrap Diode with a High-Accuracy keeping the outputs off while sensing the dV/dt Oscillator of High dV/dt Immunity current of the half-bridge switching node. ADTA Operates up to 600kHz features an easier design, lower EMI, and Latched to Disable Input for Easy Protection higher efficiency. Remote On/Off Control and Brown-Out The HR1001L incorporates anti-capacitive Protection through BO mode protection, which prevents potentially Programmable Burst Mode Operation at destructive capacitive mode switching if the Light Load output is shorted or has a severe overload. Non-Linear Soft Start for Monotonic Output This feature protects the MOSFET during Voltage Rise abnormal conditions, making the converter Available in a SOIC-16 Package robust. APPLICATIONS The HR1001L has a programmable oscillator that sets both the maximum and minimum LCD and PDP TVs switching frequencies. It starts up at a Desktop PCs and Servers programmed maximum switching frequency Telecom SMPS and decays until the control loop takes over to AC/DC Adapter, Open-Frame SMPS prevent excessive inrush current. Video Game Consoles The HR1001L enters controlled burst mode at Electronic Lighting Ballast light loads to minimize the power consumption All MPS parts are lead-free, halogen-free, and adhere to the RoS directive.
