製品概要

概要

The PM7060 is an integrated power stage solution optimized for synchronous buck applications to offer high current, high efficiency, and high power density performance. Packaged in 5x6 mm QFN package, the PM7060 enables voltage regulator design to deliver in excess of 60 A per phase current. The internal power MOSFETs utilize state-of-the-art technology that delivers industry benchmark performance to significantly reduce switching and conduction losses.

The PM7060 incorporates an advanced MOSFET gate driver IC that features high current driving capability, adaptive deadt-time control, and integrated bootstrap switch, a thermal monitor that alerts the system of excessive junction temperature. This driver is compatible with 3.3 V logic PWM with tri-state to manage High Impedance Output. Diode emulation mode can be enabled at light loads through the use of GLCTRL signal.

The device also integrates a current monitor to provide a real-time scale down of inductor current (IMON). A temperature monitor provides the system with an indication of the power stage internal temperature (TMON) and can be used to throttle the system operation down to a safer level if needed.

The device also integrates fault alerts such as HS FET overcurrent, overtemperature and HS MOSFET short failures.
