The ISL62381, ISL62382, ISL62383 family of controllers generate supply voltages for battery-powered systems. The ISL62381 and ISL62382 include two pulse-width modulation (PWM) controllers, adjustable from 0.6V to 5.5V, and two linear regulators, LDO5 and LDO3, that generate a fixed 5V and an adjustable output respectively, and each can deliver up to 100mA. The ISL62383 has the same outputs as the ISL62381 and ISL62382, but without LDO3 linear regulator. The channel 2 switching regulator will automatically take over the LDO5 load when programmed to 5V output. This provides a large power savings and boosts efficiency. The ISL62381, ISL62382, ISL62383 family include on-board power-up sequencing, two power-good (PGOOD) outputs, digital soft-start, and internal soft-stop output discharge that prevent negative voltages on shutdown.
