HR1000 Resonant Half-Bridge Controller DESCRIPTION The HR1000 is a controller designed specifically for the resonant half-bridge topology. It provides two drive-signal channels that output plementary signals at a 50% duty cycle. An internal fixed dead-time of 350ns between the two plementary gate signals guarantees zero-voltage switching during the transient and enables high-frequency operation. The integrated bootstrap diode simplifies the external driving circuit for the high-side switch. It can withstand up to 600V with immunity against high dV/dt noise. Modulating the switching frequency regulates the topology output voltage. A programmable oscillator can set both the maximum...
