描述

The EL7516 is a high frequency, high efficiency step-up voltage regulator operated at constant frequency PWM mode. With an internal 1. 5A, 200mΩ MOSFET, it can deliver up to 600mA output current at over 90% efficiency. The selectable 600kHz and 1. 2MHz allows smaller inductors 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 10µA of current and can operate down to 2. 5V input supply. These features along with 1. 2MHz switching frequency makes it an ideal device for portable equipment and TFT-LCD displays. The EL7516 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.

    AN1101: Designing a High Efficiency DC-DC Converter with the EL75XX
    PDF 817 KB an1101 2003年4月15日
    AI 生成的摘要: The document details the design of a high-efficiency DC-DC converter using the EL75XX series. It explains the pin functions, including charge pump capacitors, voltage doubler input, ground connections, and control signals. The basic buck regulator topology is described, showing how the output voltage depends on input voltage and duty cycle. It also covers synchronized rectification, replacing diodes with low-resistance FETs to improve efficiency and reduce power loss, with the addition of a Schottky diode to enhance reliability during transient states.

    AN1096: Thermal Design Considerations—EL75XX
    PDF 453 KB an1096 2003年4月15日
    AI 生成的摘要: The document details thermal design considerations for the EL75XX series, focusing on the 28 PSOP 2 package. It explains two versions of the package—slug down and slug up—with different mounting and heat dissipation options. Various heatsink configurations, bonding materials, and forced air convection methods improve thermal performance, enabling power dissipation from 2W up to 9W. Thermal resistance values and the effects of airflow on heat dissipation are analyzed with graphical data.
