Description
The PM7080A is an integrated power stage solution optimized for synchronous buck
applications to offer high current, high efficiency, and high power density solution.
Packaged in 5x6 mm QFN package, the PM7080A enables voltage regulator design
to deliver above 110 A per phase peak current.
The internal power MOSFETs utilize state-of-the-art technology that delivers industry
benchmark performance to significantly reduce switching and conduction losses.
The PM7080A incorporates an advanced MOSFET gate driver IC that features high
current diving capability, adaptive dead-time control and integrated bootstrap switch
to enable high frequency switching up to 1.5MHz.
The device incorporates an innovative inductor current emulation algorithm with
thermal compensation to achieve best-in-class reporting accuracy. It also includes
a temperature monitor function with 2% accuracy. The PM7080A provides
comprehensive protection features, including cycle-by-cycle over-current protection,
over-temperature protection, high-side MOSFET short protection, VIN/VCC/VDRV/
BOOT UVLO protection. In addition to their analog reporting capability, the combined
logic outputs of IMON and TMON provide fault mapping to the PWM controller for
specific fault condition deciphering.
The PM7080A is compatible with industry-standard footprint.
