... General Description The AP1512 monolithic IC designed for use as a step-down DC/DC converter with the ability of driving a 2A (3A for AP1512A) load without additional transistor components. The board space is reduced since AP1512/A requires few external components. The external shutdown function is controlled by logic level and can be put into standby mode. The internal compensation ensures feedback control has good line and load regulation without external design ...
