描述

The ISL8560 is a step down DC/DC power switching regulator which accepts 9.0V to 60V input and provides a 2A output current. The output voltage can be set in the range between 1.21V and 55V by means of an external divider. The device uses an internal power DMOS transistor with a typical rDS(ON) of 0.19Ω to obtain very high efficiency and high switching speed. A switching frequency in the range of 100kHz to 600kHz can be realized (the maximum power dissipation of the various packages must be observed). Notable features of this next generation of DC/DC converter includes pulse-by-pulse current limit for FET protection, hiccup mode for short circuit protection, voltage feedforward regulation, Frequency SYNC, soft-start, low standby current of 60µA typical in the disabled state, and thermal shut-down. The device is available in a 20 Ld QFN package.

    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.
