产品概述 返回TOP
The CXSB6616 is a high performance buck boost converter that the output voltage can be programedfrom 0.9V up to 20V through external resistor. The CXSB6616 implements the Buck Boost converter with a single inductor architecturethat 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, maximizesefficiency, 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. CXSB6616 guarantees robustness with under voltage lockout, short circuit protection and thermal protection.
