The LM5017 is a 100-V, 600-mA synchronous stepdown 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 high step-down ratios. The on-time varies inversely with the input
voltage resulting in nearly constant frequency over the input voltage range. A high
voltage startup regulator provides bias power for internal operation of the IC and
for integrated gate drivers.
A peak current limit circuit protects against overload conditions. The undervoltage
lockout (UVLO) circuit allows the input undervoltage threshold and hysteresis to be
independently programmed. Other protection features include thermal shutdown and
bias supply undervoltage lockout (VCC UVLO).
The LM5017 device is available in WSON-8 and HSOP PowerPAD-8 plastic packages.
