Power Integrations, Inc. Full, Half-Bridge (H Bridge) Drivers LCS708HG

The LCS708HG from Quarktwin Technology Ltd. is a full half-bridge driver 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 half-bridge configuration, allowing for a compact design that reduces the need for up to 30 external components. The device supports a maximum operating frequency of 1 MHz and nominal steady-state operation up to 500 kHz, which can significantly minimize the size of magnetics and enable the use of surface-mount ceramic output capacitors. This driver features precise duty symmetry, comprehensive fault handling, and various protection mechanisms, including undervoltage, overvoltage, over-current, short-circuit, and over-temperature protection. It also offers programmable parameters such as brown-in/out thresholds, dead-time, soft-start time, and frequency limits, enhancing design flexibility. The LCS708HG is suitable for applications in high-efficiency power supplies, LCD TV power supplies, LED lighting, and audio amplifiers, making it a versatile choice for engineers seeking reliable performance in demanding environments.
