Texas Instruments LM25018
the LM25018 with the WEBENCH® Power Designer 2 Applications • Industrial equipment • Smart power meters • Telecommunication systems • Isolated bias supply (Fly-Buck™) 3 Description The LM25018 device is a 48-V, 325-mA synchronous step-down regulator with integrated high-side and low-side MOSFETs. The constant on-time (COT) control scheme employed in the LM25018 device requires no loop compensation, provides excellent transient response, and enables very high step-down ratios. The on-time varies inversely with the input voltage resulting in nearly constant frequency over the input voltage range.
