描述
The ISL62381, ISL62382, ISL62383, ISL62381C, ISL62382C and ISL62383C family of controllers generate supply voltages for battery-powered systems. These controllers 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 and ISL62383C have the same outputs as the ISL62381, ISL62382, ISL62381C and ISL62382C 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. These controllers include onboard power-up sequencing, two power-good (PGOOD) outputs, digital soft-start, and internal soft-stop output discharge that prevent 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 ISL62381, ISL62382, ISL62381C and ISL62382C are available in a 32 Ld 5x5 TQFN package, and the ISL62383 and ISL62383C are available in a 28 Ld 4x4 TQFN package. This family of controllers can operate over the extended temperature range (-10°C to +100°C).
