If the input voltage is equal to or less than the output voltage Is there a pass-through function?

Gareth,

The converter will go into 99% duty cycle when input voltage is less than setpoint output voltage.

The high-side FET will be on 99+% of the time such that VOUT≈VIN.

Hope this helps,

Hi Orlando

Does it have the same PassThru 100% Duty Cycle Capable function as LTC7803?

Hi Gareth,

No this device does not have 100% duty cycle capability.

Our maximum duty cycle will be 99-99.9% depending on switching frequency.

Hope this helps,
