ISL81805 80V Dual Synchronous Boost Controller Renesas Electronics ISL81805 80V Dual Synchronous Boost Controller generates two independent outputs or one output with two interleaved phases for various industrial and general-purpose applications. A wide input/output voltage range makes the controller suitable for telecommunications, data centers, and computing applications. Packaged in a space-conscious 32-lead 5mm x 5mm TQFN, the controller features programmable soft-start and accurate threshold enable functions with a power-good indicator to simplify power supply rail sequencing. To ensure high reliability, the device also provides full protection features such as OVP, UVP, OTP, and average and peak current limits on both outputs.
