80V 双相同步氮化镓场效应晶体管降压控制器评估板
ISL81806EVAL1Z 双相评估板采用 ISL81806,这是一款针对加强型氮化镓场效应晶体管进行优化的 80V 高压双相同步降压控制器,可提供外部软启动、独立启用功能和 UV/OV/OC/OT 保护功能。 100kHz 至 2MHz 的可编程开关频率帮助优化电感尺寸,强大的栅极驱动器提供保证 20A 的降压输出。
The ISL81806 is a E-mode GaN based dual synchronous buck controller that generates two independent outputs or one output with two interleaved phases. With wide input and output voltage ranges up to 80V, the controller is suitable for telecommunication, data center, and computing applications.
The ISL81806 provides gate driver voltage of 5.3V to meet E-mode GaN device applications. The ISL81806 uses peak current mode control with phase interleaving for the two outputs. Each output has a voltage regulator, current monitor, and average current regulator to provide independent average voltage and current control. The internal Phase-Locked Loop (PLL) oscillator assures an accurate frequency setting from 100kHz to 1MHz, and the oscillator can be synchronized to an external clock signal for frequency synchronization and phase interleave paralleling applications. This PLL circuit can output a phase-shift-programmable clock signal
that is expanded to three, four, and six phases.
The ISL81806 features programmable soft-start and accurate threshold enable functions along with a power-good indicator to simplify power supply rail sequencing. It also provides full protection features such as OVP, UVP, OTP, and OCP on both outputs. The IC is packaged in a space- saving 32 Ld 5mm × 5mm TQFN with an EPAD.
