About This Video

Designed to meet the rigorous power management demands of emerging 48V architectures, the Renesas ISL81801 and ISL81802 represent a significant step forward for 5G telecom, computing, and industrial power design. The ISL81801 is an 80V bidirectional buck-boost controller built for applications requiring flexible power flow in both directions, while the ISL81802 is a dual-output, two-phase synchronous buck controller packed with advanced features for high-efficiency step-down conversion. Both devices support constant current and constant voltage regulation, making them well suited for battery charging systems, renewable energy installations, automotive power rails, and a broad range of wide input or wide output industrial applications. Learn how these solutions can simplify your power architecture design while delivering the performance and reliability required in today's most demanding environments.
