TPS62162: Vout is always 3.24V， can't get 3.3V

Part Number: TPS62162
Other Parts Discussed in Thread: TPS62160

Hi Team,

Our customer is using TPS62162, the Vin is 5V~6V, but the Vout is kept at 3.24V, can't reach 3.3V, even in empty-load and light-load condition. Could you help to give some comments? The schematic and Inductance is as below. Thanks a lot.

David,

Initial accuracy is +/- 3%. 3.24 V output is within that range.

Hi JohnTucker：

If I use the adjustsable output TPS62160.
Whether the efficiency is consistent with the fixed output TPS62162?

My output voltage is 3V3.

Best Regards.

David,

The only difference in efficiency is the addition of the external feed back resistors. The power loss associated with the resistor divider should be very small, around 18 uW.
