LTM4673: Can Channel 1 be enabled by hardware by default at power-up without PMBus configuration?

Category: Hardware
Product Number: LTM4673

Hello,

I am using the LTM4673 Quad Output μModule Regulator with Digital Power System Management in a design with the four outputs configured at different voltages.

I would like to enable Channel 1 / VOUT1 automatically by hardware when the board powers up, without having to configure the device through PMBus.

In other words, if I connect CONTROL1 to VDD33 through a pull-up resistor, and VIN/VINSNS exceeds VIN_ON, will VOUT1 start automatically after the default TON_DELAY, assuming the factory default OPERATION

Thank you.
Umberto.
