DATASHEET ISL62381, ISL62382, ISL62383, ISL62381C, ISL62382C, ISL62383C FN6665 Rev 6.00 High-Efficiency, Quad or Triple-Output System Power Supply Controller for Notebook October 23, 2015 Computers The ISL62381, ISL62382, ISL62383, ISL62381C, ISL62382C Features and ISL62383C family of controllers generate supply voltages 3 High Performance R Technology for battery-powered systems. These controllers include two Fast Transient Response pulse-width modulation (PWM) controllers, adjustable from 0.6V to 5.5V, and two linear regulators, LDO5 and LDO3, that 1% Output Voltage Accuracy: -10C to +100C generate a fixed 5V and an adjustable output respectively, and Two Fully Programmable Switch-Mode Power Supplies with each can deliver up to 100mA. The ISL62383 and ISL62383C Independent Operation have the same outputs as the ISL62381, ISL62382, ISL62381C Programmable Switching Frequency and ISL62382C but without LDO3 linear regulator. The channel Integrated MOSFET Drivers and Bootstrap Diode 2 switching regulator will automatically take over the LDO5 load Adjustable (+1.2V to +5V) LDO Output when programmed to 5V output. This provides a large power Fixed +5V LDO Output with Automatic Switchover to SMPS2 savings and boosts efficiency. These controllers include on- Internal Soft-Start and Soft-Stop Output Discharge board power-up sequencing, two power-good (PGOOD) outputs, digital soft-start, and internal soft-stop output discharge Wide Input Voltage Range: +5.5V to +25V that prevent negative voltages on shutdown. Full and Ultrasonic Pulse-Skipping Mode 3 Power-Good Indicator The patented R PWM control scheme provides a low jitter system with fast response to load transients. Light-load Overvoltage, Undervoltage and Overcurrent Protection efficiency is improved with period-stretching discontinuous Fault Identification by PGOOD Pull-Down Resistance conduction mode (DCM) operation. To eliminate noise in Thermal Monitor and Protection audio frequency applications, an ultrasonic DCM mode is Pb-Free (RoHS Compliant) included, which limits the minimum switching frequency to approximately 28kHz. Applications The ISL62381, ISL62382, ISL62381C and ISL62382C are Notebook and Sub-Notebook Computers available in a 32 Ld 5x5 TQFN package, and the ISL62383 PDAs and Mobile Communication Devices and ISL62383C are available in a 28 Ld 4x4 TQFN package. 3-Cell and 4-Cell Li+ Battery-Powered Devices This family of controllers can operate over the extended General Purpose Switching Buck Regulators temperature range (-10C to +100C).
