AP1507-D5-13

AP1507-D5-13 is a AP1507 series monolithic IC designed for a step-down buck DC/DC converter. 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 go into standby mode. The internal compensation makes the feedback control have good line and load regulation without an external design. Regarding the protected function, the thermal shutdown prevents overtemperature operation from damaging the device, and current limit protects against overcurrent operation of the output switch. If the current limit function occurs, and VFB is down to 0.5V below, the switching frequency reduces.
