Dear forum,
We are testing the TPS61240 using EV board for our product. Our product contains a load of 150mA, which is switched on every 1ms for only 50uS. According to the datasheet, the TPS61240 should handle this well. Unfortunately when we use it, the device draws continuously around 290 mA. We have added 22 uF both on the input and output lines and the TPS61240 and the voltages look stable on the oscilloscope. Any idea what could be causing this excessive current? When the TPS61240 is bypassed, the current draw is normal.
Best regards,
