AP1507 - 3A PWM BUCK DC/DC CONVERTER

General Description

The AP1507 is a monolithic IC designed for a step-down DC/DC converter and is capable of driving a 3A load without an external transistor.

Due to reducing the number of external components, the board space can be saved easily.

Key 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. Features.
  • Output Voltage: 3.3V, 5V, 12V and Adjustable Output Version.
  • Adjustable Version Output Voltage Range, 1.23V to 18V ±4%.
  • 150kHz ±15% Fixed Switching Frequency.
  • Voltage Mode Non-.

NOT RECOMMENDED FOR NEW DESIGN CONTACT US AP1507 150kHz, 3A PWM BUCK DC/DC CONVERTER Description The AP1507 is a monolithic IC designed for a step-down DC/DC converter and is capable of driving a 3A load without an external transistor. Due to reducing the number of external components, the 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 external design. Regarding the protected function, the thermal 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.
