描述

The ISL97519A is a high frequency, high efficiency step-up voltage regulator operated at constant frequency PWM mode. With an internal 2. 0A, 200mΩ MOSFET, it can deliver up to 1A output current at over 90% efficiency. Two selectable frequencies, 600kHz and 1. 2MHz, allow trade offs between smaller components and faster transient response. An external compensation pin gives the user greater flexibility in setting frequency compensation allowing the use of low ESR Ceramic output capacitors. When shut down, it draws <1µA of current and can operate down to 2. 3V input supply. These features, along with 1. 2MHz switching frequency, make it an ideal device for portable equipment and TFT-LCD displays. The ISL97519A is available in an 8 Ld MSOP package with a maximum height of 1. 1mm. The device 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.
