AP1501 150Khz, 3A PWM Buck DC/DC Converter Features – Output voltage: 3.3V, 5V, 12V and adjustable output version – Adjustable version output voltage range, 1.23V to 37V+4% – 150Khz +15% fixed switching frequency – Voltage mode non-synchronous PWM control – Thermal-shutdown and current-limit protection – ON/OFF shutdown control input – Operating voltage can be up to 40V – Output load current: 3A – TO220-5L TO220-5L(R) and TO263-5L packages – Low power standby mode – Built-in switching transistor on chip General Description The AP1501 series are monolithic IC that design for a step-down DC/DC converter, and own the ability of driving a 3A load without additional transistor component. Due to reducing the number of external component, 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. Regardin […]
