TPS61022: Higher Vin_min at higher loads?

Part Number: TPS61022

Hello,

The PMP30528 suggests that Vout goes to zero when Vin is below 1.8V at 2A load (see 2.4.1 and 2.4.2 in test report of PMP30528). Is that a general behavior of the TPS61022?

Hi Kaya,

TPS61022 Vout should be at 3.9V when Vin is at around 1.8V because TPS61022 switch valley current limit is at least 6.5A. I'll contact this PMP designer to discuss this behavior. Thanks for reminding it.
