Texas Instruments LM25017
the LM25017 with the WEBENCH® power designer 2 Applications • Industrial equipment • Smart power meters • Telecommunication systems • Isolated bias supply (Fly-Buck™) 3 Description The LM25017 device is a 48-V, 650-mA synchronous step-down regulator with integrated high-side and low-side MOSFETs. The constant on-time (COT) control scheme employed in the LM25017 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.
