TLV61046A: Maximum duty cycle/passthrough mode

Nicholas Carley

Part Number: TLV61046A
Other Parts Discussed in Thread: TLV61046

Hello,

What happens to this device as the input voltage approaches the target output voltage (ie if Vin = 3.3V and Vout = 3.3V)?

The datasheet doesn't address a maximum duty cycle or a passthrough operation mode.

Thanks,
Nick

Hi Nick：

That's no problem as the device has PFM. It will change the frequency in some way with light load or Vin to close to Vout. (But not means Vin much higher than Vout)

Actually, I don't recommend to use TLV61046 for such low Vout target.
