The ISL62386 controller generates supply voltages for battery-powered systems. The ISL62386 includes 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 output and a fixed 3. 3V output respectively. Each can deliver up to 100mA. The Channel 2 switching regulator will automatically take over the LDO5 load when programmed to 5V output. This provides a large power saving and boosts efficiency. The ISL62386 includes on-board power-up sequencing, one power-good (PGOOD) output, digital soft-start, and an internal soft-stop output discharge that prevents negative voltages on shutdown. The patented R3 PWM control scheme provides a low jitter system with fast response to load transients. Light-load efficiency is improved with period-stretching discontinuous conduction mode (DCM) operation. To eliminate noise in audio frequency applications, an ultrasonic DCM mode is included, which limits the minimum switching frequency to approximately 28kHz. The ISL62386 is available in a 32 Ld 5mm x 5mm TQFN package, and can operate over the extended temperature range (-10 °C to +100 °C).
