宽范围输入双相直流-直流同步降压控制器ADP1850数据表

　　The ADP1850 is a configurable dual output or two-phase， single output dc-to-dc synchronous buck controller capable of running from commonly used 3.3 V to 12 V （up to 20 V） voltage inputs. The device operates in current mode for improved transient response and uses valley current sensing for enhanced noise immunity. The architecture enables accurate current sharing between interleaved phases for high current outputs. The ADP1850 is ideal in system applications requiring multiple output voltages： the ADP1850 includes a synchronization feature to eliminate beat frequencies between switching devices; provides accurate tracking capability between supplies and includes precision enable for simple， robust sequencing

　　The ADP1850 provides high speed， high peak current drive capability with dead-time optimization to enable energy efficient power conversion. For low load operation， the device can be configured to operate in power saving mode （PSM） by skipping pulses and reducing switching losses to improve the energy efficiency at light load and standby conditions. The accurate current limit （±6%） allows the power architect to design within a narrower range of tolerances and can reduce overall converter size and cost.
