Product Description
The HR1001C is an enhanced LLC controller that provides adaptive dead-time adjustment (ADTA) and capacitive mode protection (CMP) features, as well as functional improvements on surge performance. ADTA inserts a dead time between the two complimentary gate outputs automatically. This is ensured by keeping the outputs off while sensing the dV/dt current of the half-bridge switching node. ADTA features easier design, lower EMI, and higher efficiency. The HR1001C 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 HR1001C 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 HR1001C enters a controlled burst mode at light load to minimize power consumption and tighten the output regulation. Full protection features include two-level over-current protection (OCP) with external latch shutdown, auto-recovery, brown-in and brown-out, capacitive mode protection (CMP), and over-temperature protection (OTP), improving converter design safety with minimal extra components.
