Product Description

      XXL1509 is a high-efficiency step-down DC-DC power converter with a fixed 150KHz switching frequency. It can provide 3A output current capability, low ripple, excellent linear regulation and load regulation.

      XXL1509 has a built-in fixed frequency oscillator and frequency compensation circuit, which simplifies the circuit design.

      The PWM control loop can adjust the duty cycle linearly from 0 to 100%.

      Built-in enable function and output over-current protection function. When the secondary current limiting function is enabled, the switching frequency drops from 150KHz to 50KHz. The internal compensation module can reduce the number of peripheral components.
