The XLSEMI XL1509-3.3E1 is a fixed-frequency PWM buck DC/DC converter designed to provide a stable 3.3V output. It is suitable for general-purpose step-down power supply applications, offering a maximum output current of 2A.
Key electrical specifications include an input voltage range of 4.5V to 40V and a switching frequency of 150kHz. The converter also features a 100% maximum duty cycle and includes internal thermal and current limit protection for enhanced reliability.
This component is well-suited for consumer electronics and networking equipment. Engineers should pay close attention to PCB layout guidelines, particularly ensuring a short ground path away from the Schottky diode to mitigate switching noise. The XL1509-3.3E1 is currently active and widely available with no significant supply chain risks reported.
