TC7662A集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

TC7662A属于集成电路（IC）的稳压器-DC-DC开关稳压器。由美国微芯科技公司制造生产的TC7662A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。

GENERAL DESCRIPTION

The TC7662A is a pin-compatible upgrade to the In dustry standard TC7660 charge pump voltage converter. It converts a +3V to +18V input to a corresponding – 3V to -18V output using only two low-cost capacitors, eliminating inductors and their associated cost, size and EMI. In addition to a wider power supply input range (3V to 18V versus 1.5V to 10V for the TC7660), the TC7662A can source output currents as high as 40mA. The on-board oscillator operates at a nominal frequency of 12kHz. Operation be low 10kHz (for lower supply current applications) is also possible by connecting an external capacitor from OSC to ground.
