TPS61200: TPS61220 Minimum load current

Part Number: TPS61220
Other Parts Discussed in Thread: TLV61220, TPS61200, , TPS61094


 For our application we need a boost converter whose input voltage should be less than or equal to 2V and greater than 3.5V. The maximum output current can be more than 300mA.

With TLV61220, when connected with a load less than 10mA  the boost converter consumes more than 27mA as mentioned in the picture below.

When connected with load greater than 30mA it works fine. It takes a constant load of 30mA. Why is it so? Is there anything like minimum load current?.

Our requirement is that we need boost converter to work in two circumstances, 1) Lighter loads @ less than 1 mA      2) Heavy loads greater than or equal to 300mA.
