Product Overview

The AP1509-33SG-13 is a PWM Buck DC/DC Converter that owns the ability of driving a 2A load without additional transistor. It saves board space. The external shutdown function can be controlled by logic level and then come into standby mode. The internal compensation makes feedback control having 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 occurs and VFB is down below 0.5V, the switching frequency will be reduced. The AP1509 series operates at a switching frequency of 150kHz thus allow 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.
  • Adjustable version output voltage range, 1.23 to 18V + 4%
  • 150kHz +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 22V
  • Low power standby mode
  • Built-in switching transistor on chip
