MP6519

The MP6519 is a monolithic, step-down, current-source driver for applications that require accurate and fast current-response control. The MP6519 achieves up to 5A of output current with excellent load and line regulation over a wide input supply range.

The four integrated MOSFET H-bridge control provide a fast dynamic load response and an ultra-high efficiency solution. For ease of use, the output polarity can be controlled by pulling MODE high or low.

By setting the full-scale output current through an external resistor, the output current can be dimmed by the PWM input signal from 0 - 100% of the full-scale current range.

Full protection features include load open, loadshort protection, over-current protection (OCP), over-temperature protection (OTP), and input over-voltage protection (OVP). The MP6519 is available in a QFN-19 (3mmx3mm) package.
