ADP2441ACPZ

开关稳压器 36V 1A Sync Step-Down

36 V,1 A, Synchronous, Step-Down DC-to-DC Regulator

GENERAL DESCRIPTION ADP2441ACPZ

The ADP2441 is a constant frequency, current mode control, synchronous, step-down dc-to-dc regulator that is capable of driving loads up to 1 A with excellent line and load regulation characteristics. The ADP2441 operates with a wide input voltage range of 4.5 V to 36 V, which makes it ideal for regulating power from a wide variety of sources. In addition, the ADP2441 has very low minimum on time (50 ns) and is, therefore, suitable for applications requiring a very high step-down ratio.
