Part Number: TPS61099

Team,

Do we have boost converter which can achieve >95% at 30~60mA output? Input is VBAT and output is 4.6~5V. Which device has the best light load efficiency?

Regards,

Hi Nic:
What's the range of VIN/VBAT ?

VBAT is around 3~4.35V and output 4.6~5V.

Hi Nic:
We have tested in our lab. The efficiency was about 93% @Vin=3V, and 95%@Vin=4.2V. Room temperature, typical value,Io=60mA.
You could contact me with email if you need more data.
