ST735集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

ST735属于集成电路（IC）的稳压器-DC-DC开关稳压器。由意法半导体集团制造生产的ST735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。

DESCRIPTION

The ST735 is a Bi-CMOS, inverting switch mode DC-DC regulator with internal Power MOSFETs that generates a fixed -5V output voltage from a 4V to 6.2V input voltage; is guaranteed an output current of 200mA for inputs greater than 4.5V. The quiescent current for this device is typically of 0.8mA and, in shutdown mode it is reduced to 10µA.
