Description
The
PSA60
is a high performance digital controller featuring the innovative and
patented resonant / non-resonant ST VCOT™ control loop that allows to implement a
high efficiency DC-DC converter in single-stage conversion directly from the 60 V
bus.
In combination with PSA satellites, the device is able to implement a scalable power
supply with output power in excess of 1 kW featuring Auto Cell Shedding and PFM to
optimize the overall efficiency maintaining a >90% baseline over the whole current
range without compromising the load transient and DVID response.
The
PSA60
can be fully configured through PMBus™ to minimize external
component count. Full set of telemetry is provided including BBR, CFP and primary /
secondary side telemetry.
The device assures fast and independent protection against overcurrent, over/under-
voltage and FB disconnection.
The
PSA60
is available in VFQFPN68, 8x8 mm package with exposed pad.
