描述 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/undervoltage

and FB disconnection.

The STPDDC60 is available in VFQFPN68, 8x8 mm package with exposed pad.
