產品介紹The ZL1507 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 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. Regarding protected function, thermal shutdown is to prevent over temperature operating from damage, and current limit is against 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 ZL1507 series operates at a switching frequency of 150KHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. 產品屬性 Output voltage: 3.3V, 5V, 12V and adjustable output version Adjustable version output voltage range, 1.23V to 18V Output load current: 3A Operating voltage can be up to 24V 150KHz fixed switching frequency Low power standby mode Frequency Fold Back at Short Circuit 其他說明Applications 產品應用 Simple High-efficiency step-down regulator On-card switching regulators Positive to negative converter 交易說明Please directly contact us, thank you！
