NOT RECOMMENDED FOR NEW DESIGN CONTACT US AP1507 150kHz, 3A PWM BUCK DC/DC CONVERTER Description Pin Assignments The AP1507 is a monolithic IC designed for a step-down DC/DC (Top View) converter and is capable of driving a 3A load without an external transistor. Due to reducing the number of external components, the 5 SD 4 FB 3 GND 2 Output 1 VIN 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 Metal Tab GND external design. Regarding the protected function, the thermal TO252-5 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. The AP1507 series operates at a switching frequency of 150kHz, which allows smaller-sized filter components than the requirements 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 included a fixed 3.3V, 5V, 12V, and an adjustable type. AP1507 is available in a 5-lead TO252-5 green package.
