LCS700LG

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. The variable frequency controller provides high-efficiency by switching the power MOSFETs at zero voltage (ZVS), eliminating switching losses. LLC half-bridge power stage incorporating controller, high and low-side gate drives and high-voltage power MOSFETs eliminates up to 30 external components. Programmable burst mode maintains regulation at no-load and improves light load efficiency. Single package designed for high-power and high-frequency reduces assembly cost and reduces PCB layout loop areas. Paired with HiperPFS PFC product gives complete, high efficiency, low part count PSU solutions. Applications includes high-efficiency power supplies (80 PLUS silver, gold and platinum), LCD TV power supplies, LED street and area lighting, printer power supplies and audio amplifier.

• Maximum practical power of 110W
• High maximum operating frequency of 1MHz, nominal steady-state operation up to 500KHz
• Dramatically reduces magnetics size and allows use of SMD ceramic output capacitors
• Precise duty symmetry balances output rectifier current, improving efficiency
• Comprehensive fault handling and current limiting, programmable brown-in/out thresholds, hysteresis
• Undervoltage (UV) and overvoltage (OV) protection, programmable overcurrent protection (OCP)
• Short-circuit protection, overtemperature protection, programmable dead-time for optimized design
• Accurate programmable minimum and maximum frequency limit
• Programmable soft-start time and delay before soft-start
• Staggered pin arrangement for simple PC board routing and high voltage creepage requirements
