TCM829中文资料Charge Pump DC-to-DC Converters数据手册Microchip规格书

描述 Description

TCM828/829 are CMOS \"charge-pump\" voltage converters in ultra-small 5-Pin SOT-23A packages. They invert and/or double an input voltage which can range from +1.5V to +5.5V. Conversion efficiency is typically >95%. Switching frequency is 12kHz for the TCM828 and 35kHz for the TCM829.External component requirement is only two capacitors (3.3µF nominal) for standard voltage inverter applications.With a few additional components a positive doubler can also be built. All other circuitry, including control, oscillator, power MOSFETs are integrated on-chip.Supply current is 50µA (TCM828) and 115µA (TCM829).The TCM828 and TCM829 are available in a 5-Pin SOT-23A surface mount package.

简介

TCM829属于集成电路（IC）的稳压器-DC-DC开关稳压器。由制造生产的TCM829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。
