Description

The STPDDC60 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 STPRDC01 and STPRDC02, the device is able to implement a

scalable power supply with output power ranging from 50 W up to >300 W 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 STPDDC60 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 STPDDC60 is available in VFQFPN68, 8x8 mm package with exposed pad.
