Description

The AL8890Q/AL88902Q is a synchronous buck converter with internal compensation and switching frequency adjustable up to 2.5MHz. The device integrates a 120mΩ high-side power MOSFET and a 55mΩ low-side power MOSFET to provide high-efficiency DC-DC conversion.

The AL8890Q enables a continuous load current of up to 3.5A, (AL88902Q up to 2.5A) with efficiency as high as 95% in enhanced biased. The device features current mode control operation, which enables easy loop stabilization supporting a wide range of output loading, suitable for both CV (Constant Voltage) and CC (Constant Current) applications.

The AL8890Q/AL88902Q simplifies board layout and reduces space requirements with its high switching frequency and use of smaller size inductor and built-in MOSFET, making it ideal for power management.

The AL8890Q/AL88902Q is available in both TSSOP-16EP and wettable U-QFN4040-16/SWP (Type UXB) packages.
