ISL62391 Overview
It includes two pulse-width modulation (PWM) controllers, adjustable from 0.6V to 5.5V, and a linear regulator (LDO3) that generates a fixed 3.3V and can deliver up to 100mA. The ISL62391, ISL62392, ISL62391C and ISL62392C include on-board power-up sequencing, a power-good (PGOOD) output, digital soft-start, and internal soft-stop output discharge that prevents negative voltages on shutdown. The patented R3 PWM...
