LM5017SD/NOPB

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.
