L4960H集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

L4960H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L4960H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 L4960 is a monolithic power switching regulator delivering 2.5A at a voltage variable from 5V to 40V in step down configuration.

Features of the device include current limiting, soft start, thermal protection and 0 to 100 duty cycle for continuous operation mode.

TheL4960 is mountedina Heptawattplastic power package and requires very few external components.

Efficient operation at switching frequencies up to 150KHz allows a reduction in the size and cost of external filter components.
