STPDDC60数据手册ST中文资料规格书

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/under-voltage and FB disconnection.

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