SI9102集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

SI9102属于集成电路（IC）的稳压器-DC-DC开关稳压器。由威世科技半导体制造生产的SI9102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 Si9102 high-voltage switchmode regulator is a monolithic

BiC/DMOS integrated circuit which contains most of the

components necessary to implement a high-efficiency dc-todc

converter up to 3 watts. It can either be operated from

a low-voltage dc supply, or directly from a 10 to 120 V unregulated

dc power source.

This device may be used with an appropriate transformer to

implement most single-ended isolated power converter

topologies (i.e., flyback and forward).

The Si9102 is available in both standard and lead (Pb)-free

14-pin plastic DIP and 20-pin PLCC packages which are

specified to operate over the industrial temperature range of

- 40 °C to 85 °C.
