 Description |
|
|
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.
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, is available in 32 Ld 5x5 TQFN package, and ISL62383 is available in 28 Ld 4x4 TQFN package. ISL62381, ISL62382, ISL62383 family can operate over the extended temperature range (-10°C to +100°C). |
