The Future of Analog IC Technology
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, load-
short 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.
