FEATURES
- Output voltage: 3.3V, 5V, 12V and adjustable output version - Adjustable version output voltage range, 1.23V to 37V+4% - 50KHz +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 60V - Output load current: 2A (for AP1512) 3A (for AP1512A) - Low power standby mode - Built-in switching transistor on chip - TO220-5L, TO220-5L(R) and TO263-5L Pb-free packages GENERAL DESCRIPTION
Due to reducing the number of external component, the board space can be saved easily. 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 AP1512/A operates at a switching frequency of 50KHz 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.
