Hi,
We intend to use TPS61322 in an single cell NiMH application that is Vin 1 to 1.5V and Vout 2.2V. I did a test board with the device. The load is 50ohm resistor (100//100) i..e 44mA output current. Input and output capacitors are X5R 22uF ceramics and the inductor is "DFE252012P-4R7M=P2" i.e. the first one suggested in data sheet example. Without the Schottky diode the starting voltage is 1.2V, with the diode (no snubber), it's 1.1V. I was expecting (and need) to start at 0.9V. Any suggestion on how to achieve this?
