DESCRIPTION

Constant On-time Control

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. A high voltage startup regulator provides bias

power for internal operation of the IC and for

integrated gate drivers.

No Loop Compensation Required

Ultra-Fast Transient Response

Nearly Constant Operating Frequency

Intelligent Peak Current Limit

Adjustable Output Voltage from 1.225V

Precision 2% Feedback Reference

Frequency Adjustable to 1MHz

Adjustable Undervoltage Lockout (UVLO)

Remote Shutdown

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 (V_CCUVLO).
