The HR1001L is an enhanced LLC controller that provides new, adaptive, dead-time adjustment (ADTA) and capacitive mode protection (CMP) features. The HR1001L is the OCP latch-off version of the HR1001B. ADTA inserts a dead time between the two complimentary gate outputs automatically by keeping the outputs off while sensing the dV/dt current of the half-bridge switching node. ADTA features an easier design, lower EMI, and higher efficiency. The HR1001L incorporates anti-capacitive mode protection, which prevents potentially destructive capacitive mode switching if the output is shorted or has a severe overload. This feature protects the MOSFET during abnormal conditions, making the converter robust. The HR1001L has a programmable oscillator that sets both the maximum and minimum switching frequencies. It starts up at a programmed maximum switching frequency and decays until the control loop takes over to prevent excessive inrush current. The HR1001L enters controlled burst mode at light loads to minimize the power consumption and tighten output regulation. Full protection features include two-level over-current protection (OCP), external-latch shutdown, brown-in/brown-out, capacitive mode protection (CMP), and over-temperature protection (OTP).
