Power Integrations, Inc. Full, Half-Bridge (H Bridge) Drivers LCS700LG

The LCS700LG is a half-bridge driver from Quarktwin Technology Ltd. designed for high-efficiency power supply applications. It integrates a multi-function controller, high-side and low-side gate drivers, and two power MOSFETs in a compact package, significantly reducing the need for external components,Äîup to 30 can be eliminated. The device operates at a maximum frequency of 1 MHz, with nominal steady-state operation up to 500 kHz, allowing for reduced magnetics size and compatibility with SMD ceramic output capacitors. Key features include precise duty symmetry for balanced output rectifier current, comprehensive fault handling, and multiple protection mechanisms such as undervoltage, overvoltage, over-current, short-circuit, and over-temperature protection. The LCS700LG also offers programmable parameters for dead-time, soft-start, and frequency limits, enhancing design flexibility. It is suitable for applications including high-efficiency power supplies, LCD TV power supplies, LED lighting, and audio amplifiers, making it a versatile choice for engineers seeking reliable performance in power management solutions.
