AP1506
Description
Pin Assignments
The AP1506 series are monolithic IC designed for a stepdown DC/DC converter, and own the ability of driving a 3A load without external transistor. Due to reducing the number of external ponents, the board space can be saved easily. The external shutdown function can be controlled by logic level and then e into standby mode. The internal pensation 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. If current limit function occurred and VFB is down to 0.5V below, the switching frequency will be reduced. The AP1506 series operate at a switching frequency of 150KHz thus allowing smaller sized filter ponents than what would be needed with lower frequency switching regulators. Other features include a guaranteed +4% tolerance on output voltage under...
