TC7660H中文资料High Frequency Charge Pump DC-DC Voltage Converter数据手册Microchip规格书

描述 Description

The TC7660H is a pin-compatible,high frequency up-grade to the Industry standard TC7660 charge pump voltage converter.It converts a +1.5V to +10V input to a corresponding – 1.5V to – 10V output using only two low--cost capacitors,eliminating inductors and their associated cost,size and EMI. The TC7660H operates at a frequency of 120kHz (versus 10kHz for the TC7660),allowing the use of 1.0 µF external capacitors.Oscillator frequency can be reduced (for lower supply current applications)by connecting an external capacitor from OSC to ground. The TC7660H is available in 8-pin DIP and small outline (SOIC)packages in commercial and extended temperature ranges.

简介

TC7660H属于集成电路（IC）的稳压器-DC-DC开关稳压器。由制造生产的TC7660H稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC（电源管理集成电路）产品族中的产品是元器件级设备，用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件，设备提供的电力会通过该元件。
