TPS61029: Using TPL5111EVM to test TPS61029 embedded on board *** URGENT ***

Hi Support,

Pin 1 - EN – directly connected with Vin 1.8V ~ 2.4V, without 10K pull up resistor.

Pin 8 –PS – disable Power saving mode, Pull up 10K with Vin : 1.8V ~ 2.4V.

Result :

VIN :2V, ILOAD: No Load VOUT :   4.47V

VIN :2V, ILOAD: 500mA   VOUT :   3.66V

VIN :2V, ILOAD: 550mA   VOUT :   3.29V

VIN :2V, ILOAD: 600mA   VOUT :   2.98V

This is not our expected result. We need the load current aroud 800mA above @ 3.80V.

In addition, could you advise the efficiency vs output current for TPS61029? This is not found in the datasheet.

Thanks.
