STRG06 Universal digital multicell controller with PMBus™ Data brief Applications High efficiency step down conversion Description Features High performance resonant digital control loop RVCOT ™ Drives up to 6 cells with STRG02 and STRG04, from 50 W up to > 300 W Compliant with Intel VR12.5 ™ and VR13 protocol Fully configurable through PMBus ™ Rev1.2 – Telemetry for primary and secondary – Full IC configuration / management – Voltage positioning Advanced power management – Auto cell shedding with PFM – Low power 1.8 V logic 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. Programmable protections – OV / UV and FB disconnection – Pos/neg OC per cell – Current sharing error – Black box recorder (BBR) – Catastrophic fault precursor (CFP) The STRG06 is available in a VFQFPN68, 8 x 8 mm package with an exposed pad.
