Integrated LLC Controller, High-Voltage  
Power MOSFETs and Drivers  
Product Highlights  
Description  
The HiperLCS is an integrated LLC power stage incorporating a  
multi-function controller, high-side and low-side gate drivers,  
plus two power MOSFETs in a half-bridge configuration. Figure  
1 shows a simplified schematic of a HiperLCS based power stage  
where the LLC resonant inductor is integrated into the transformer.  
Features  
•ꢀ LLC half-bridge power stage incorporating controller, high and  
low-side gate drives, and high-voltage power MOSFETs  
•ꢀ Eliminates up to 30 external components  
•ꢀ High maximum operating frequency of 1 MHz  
•ꢀ Nominal steady-state operation up to 500 kHz  
•ꢀ Dramatically reduces magnetics size and allows use of  
SMD ceramic output capacitors  
The variable frequency controller provides high efficiency by  
switching the power MOSFETs at zero voltage (ZVS), eliminating  
switching losses.  
•ꢀ Precise duty symmetry balances output rectifier current,  
improving efficiency

•ꢀ Comprehensive fault handling and current limiting  
•ꢀ Programmable brown-in/out thresholds and hysteresis  
•ꢀ Undervoltage (UV) and overvoltage (OV) protection  
•ꢀ Programmable over-current protection (OCP)  
•ꢀ Short-circuit protection (SCP)

LLC Feedback Circuit  
•ꢀ Single package designed for high-power and high-frequency  
•ꢀ Reduces assembly cost and reduces PCB layout loop areas  
•ꢀ Simple single clip attachment to heat sink  
•ꢀ Exposed thermal pad connected to ground potential – no  
insulators required between package and heat sink  
•ꢀ Staggered pin arrangement for simple PC board routing  
and high-voltage creepage requirements
