Part Number: TPS61299

Hi team,

1. At how much load curent does TPS61299 enter Burst mode and sleep status?

2. May I know the current consumption of TPS61299 under Burst mode condition and sleep status condition?

Best regards,

Hi Yamamoto，

I depends on the Input voltage and output voltage. Typically it's 6mA~10mA. Based on the bench test, 3.6V in and 5V output, the snooze enter threshold is 6mA.

About the consumption, it's hard to say because efficiency varies with the load. You can refer to the efficiency graph , 3.6V-5V conversion to calculate, note that see load current lower than 6mA.

Hi Zhong-san,

Thank you for the reply. When input voltage is 1.55V and output voltage is 3.3V, how about the snooze enter threshold? Is it still 6mA of threshold?

Best regards,

Hi Yamamoto,

for 1.55V to 3.3V conversion, the threshold is about 6mA as well .
