Performance Characteristics
Turn-on Waveform
When applying power to the LM5001 evaluation board a soft-start sequence occurs.
shows the
output voltage during a typical start-up sequence.
Conditions: Input Voltage = 28VDC, Output Current = 1A
Trace 1: Output Voltage Volts/div = 1V
Horizontal Resolution = 5ms/div
Trace 1: Output Voltage Volts/div = 1V
Horizontal Resolution = 5ms/div

Output Ripple Waveform
shows the output voltage ripple. This measurement was taken with a very short ground clip and
20 MHz bandwidth limiting.
Conditions: Input Voltage = 28VDC, Output Current = 1A,
Bandwidth Limit = 20MHZ
Trace 1: Output Ripple Voltage Volts/div = 50mV
Horizontal Resolution = 2µs/div
Bandwidth Limit = 20MHZ
Trace 1: Output Ripple Voltage Volts/div = 50mV
Horizontal Resolution = 2µs/div
