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.
