ISL62391HRTZ - Renesas Electronics

Description: The ISL62391 controller generates supply voltage for battery-powered systems. 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 includes 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 control scheme provides a low jitter system with f
