TC7660中文资料Charge Pump DC-DC Voltage Converter数据手册Microchip规格书

描述 Description

The TC7660 is a pin-compatible replacement for 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 on-board oscillator operates at a nominal frequency of 10kHz.Operation below 10kHz (for lower supply current applications)is possible by connecting an external capacitor from OSC to ground (with pin 1 open). The TC7660 is available in both 8-pin DIP and 8-pin SOIC packages in commercial and extended temperature ranges.

简介

TC7660属于集成电路（IC）的稳压器-DC-DC开关稳压器。由制造生产的TC7660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。
