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.
