STRG06 - Universal digital multicell controller with PMBus
STRG06
The STRG06 is a high performance digital controller featuring the innovative and patented ST RVCOT 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 the STRG02 and STRG04, 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 STRG06 device can be fully configured through the PMBus to minimize the external component count. A full set of telemetry is provided including the BBR, CFP and primary / secondary side telemetry.
The device assures fast and independent protection against the positive and negative OC (per cells), over/undervoltage and FB disconnection.
The STRG06 is available in a VFQFPN68, 8 x 8 mm package with an exposed pad.
