宽范围输入同步降压直流至直流控制器ADP1851数据表
分享资料个
The ADP1851 is a wide range input， 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 nominally operates in current mode with valley current sensing providing the fastest step response for digital loads. It can also be configured as a voltage mode controller with low noise and crosstalk for sensitive loads. The ADP1851 is ideal in system applications requiring multiple output voltages. The ADP1851 includes a synchronization feature to eliminate beat frequencies between switching devices. It also provides accurate tracking capability between supplies and includes precision enable and power-good functions for simple， robust sequencing.
The ADP1851 provides a high speed， high peak current gate driving capability to enable energy efficient power conversion. The device can be configured to operate in power saving mode by skipping pulses， reducing switching losses， and improving efficiency at light load and standby conditions. The accurate current limit allows design within a narrower range of tolerances and can reduce overall converter size and cost. The ADP1851 can regulate down to 0.6 V output using a high accuracy reference with ±1% tolerance over the temperature range of −40°C to +125°C.
