  • Description

    The JW®3651 is a high performance buck boost converter that the output voltage can be programmed from 0.9V up to 20V through external resistor.

    The JW3651 implements the Buck Boost converter with a single inductor architecture that operates from input voltages above, below or equal to the output voltage. And support 2-switch boost mode for higher efficiency.

    The integrated low Rds(on) MOSFET minimizes physical footprint, maximizes efficiency, which reduces the power dissipation. Constant current control is utilized to protect the device from overshooting in unwanted conditions. Built-in loop compensation simplifies the circuit and design.

    JW3651 guarantees robustness with under voltage lockout, short circuit protection and thermal protection.
