Power Management Reference Design for AMD Versal XQRVC1902
The ISLVERSALDEMO2Z demo board provides the power management for the AMD Xilinx Space Grade Versal ACAP AI Core VC1902 using Renesas' Radiation Hardened Power...
概要
説明
The ISL738841ASEH is a high-performance, radiation hardened drop-in replacement for the popular 28C4x and 18C4x PWM controllers suitable for a wide range of power conversion applications including boost, flyback and isolated output configurations. Fast signal propagation and output switching characteristics make these ideal products for existing and new designs. Features include up to 13.2V operation, low operating current, 90µA typical start-up current, adjustable operating frequency to 1MHz, and high peak current drive capability with 50ns rise and fall times.
