Rohm Productdetail
1 V to 60 V Wide-Input Dual-Phase Digital Synchronous Buck Controller with Auto-Control® & SMBus™/PMBus™ - PV2205 (新製品)
The PV2205 is a wide-input (1.0 V to 60 V) dual phase digital synchronous buck controller with adaptive loop compensation. The output can supply 0.45 V to 16 V with an input voltage up to 60 VDC, and can be configured and controlled via PMBus, with a single resistor, or through programming stored in the non-volatile memory (NVM).
This controller may be used in single or dual phase mode. When used in dual phase mode, phases may be added or removed as the load varies, so that efficiency is maximized over the load range. Additionally, the outputs of the phases are interleaved so that the effective switching frequency at the output is doubled. PV2205 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 as the phases are added and removed.
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. PV2205 is a fully protected DC/DC solution that utilizes analog and digital functionality to maximize protection of the system.
