LM5017: 100V, 600mA Constant On-Time Synchronous Buck Regulator

The LM5017 is a 100V, 600mA synchronous step-down regulator with integrated high side and low side MOSFETs. The constant-on-time (COT) control scheme employed in the LM5017 requires no loop compensation, provides excellent transient response, and enables very low step-down ratios. The on-time varies inversely with the input voltage resulting in nearly constant frequency over the input voltage range.
