EMCO ULP系列500-5000V高压电源解决方案

EMCO 公司的ULP系列是输入5.4V-7.4V输出500-5000V的高压升压电源,无负载时的功耗仅为2mW. ULP系列的输出可调和可编程,可提供4W的功率,转换效率大于85%.主要用在以电池为能源的手提仪表,雪崩光电二极管,光电倍增管,固态检测器以及电容充电等.本文介绍ULP系列主要特性和指标以及ULP系列应用电路.

The ULP Series of miniature high voltage power supplies offers orders of magnitude reduction in power consumption, enabling designers to reduce battery size and weight in portable, scientific instruments.

Standard output voltages are available from 500 volts through 5000 volts, with power consumption at full output voltage, no load, running just 2 milli-watts.

The output voltage is regulated and programmable, and is capable of delivering up to 4 watts of power on demand at a typical conversion efficiency of >85%. Its proprietary packaging results in a lightweight package weighing 2.0 ounces (typical), and features a height of only one half inch. Perfect for “green” designs, these power supplies also feature a shutdown pin which drops current consumption to less than 5 uA. Standard input voltage range is 5.4 to 7.4 volts and models are available with negative output polarity.

Designed for portable, battery powered equipment, the ULP Series is offered with a standard operating temperature range of -20oC to +70oC, and an optional extended operating temperature of -55oC to + 85oC.
