LM5122: Timing From Bypass Mode to Boost Mode

Richard Elmquist

Part Number: LM5122

Do we have any timing specifications as to how long it takes for the device to switch from Bypass Mode to Boost Mode? I cannot find anything in the data sheet that would describe this.

Thanks for your help with this!

Hi Richard,

When the LM5122 enters by-pass mode when the PWM comparator is requesting 0 on time. When this happens the high-side gate will turn on until the next pulse is needed. So there is no delay time.

Thanks,

Garrett
