Description

The AP1501A series are monolithic ICs that are designed for a step-down DC/DC converter, and possess the ability to drive a 5A 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 control°C 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. The AP1501A series operates at a switching frequency of 150Khz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Other features include a guaranteed +4% tolerance on output voltage under specified input voltage and output load conditions, and +15% on the oscillator frequency. The output version includes fixed 3.3V, 5V, 12V, and an adjustable type. The packages are available in a standard 5-lead TO263 and TO220 packages.
