描述

Support is limited to customers who have already adopted these products.

The ISL8010 is a synchronous, integrated FET 600mA step-down regulator with internal compensation. It operates with an input voltage range from 2. 5V to 5. 5V, which accommodates supplies of 3. 3V, 5V, or a Li-Ion battery source. The output can be externally set from 0. 8V to VIN with a resistive divider. The ISL8010 features automatic PFM/PWM mode control, or PWM mode only. The PWM frequency is typically 1. 4MHz and can be synchronized up to 12MHz. The typical no load quiescent current is only 120µA. Additional features include a Power-Good output, <1µA shutdown current, short-circuit protection, and over-temperature protection. The ISL8010 is available in the 10 Ld MSOP package, making the entire converter occupy less than 0. 18in2 of PCB area with components on one side only. The 10 Ld MSOP package is specified for operation over the full -40°C to +85°C temperature range.

    AN9210: A New Pspice Subcircuit For The Power MOSFET Featuring Global Temperature Options
    PDF 650 KB an9210 2001年12月21日
    AI 生成的摘要: This document presents a new PSPICE subcircuit model for power MOSFETs with global temperature options. It details synchronous rectifier circuit operation, including gate biasing and conduction modes. The model accurately simulates switching waveforms, diode recovery, and temperature-dependent efficiency. Measured and modeled data show excellent correlation for output characteristics, threshold voltage, breakdown voltage, and on-resistance across temperature ranges. Limitations in linear mode modeling are noted due to PSPICE assumptions.
