Wide-Input, Synchronous Buck Digital Controller with Auto-Control®, & SMBus™/PMBus™ for USB-PD - PV2105 (New)

The PV2105 is a wide-input (4.5 V to 28 V) digital synchronous buck controller with adaptive loop compensation, for USB-PD. The output can supply 0.6 V to 21 V with an input voltage up to 24 V, and can be configured and controlled via PMBus, with a single resistor, or through programming stored in the non-volatile memory (NVM).
PV2105 uses ROHM’s proprietary adaptive digital control loop, Auto-Control®, which adapts on a cycle-by-cycle basis, and provides active loop compensation to stabilize the control loop.
The digital functionality of this PMBus compliant power converter controller allows system telemetry (remote measurement and reporting) of current, voltage, and temperature information. Additionally, to maximize system performance and reliability, the IC provides temperature correction/compensation of several parameters. PV2105 is a fully protected DC/DC solution that utilizes analog and digital functionality to maximize protection of the system.
