AP1506-50K5L-13集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

Description

The AP1506 series are monolithic IC designed for a step down DC/DC converter, and own the ability of driving a 3A load without external transistor. Due to reducing the number of external components, the board space can be saved easily. The external shutdown function can be controlled by logic level and then come into standby mode. The internal compensation makes feedback control have good line and load regulation without external design. Regarding protected function, thermal shutdown is to prevent over temperature operating from damage, and current limit is to prevent over current operating of the output switch.
