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.
