TPS62130A: draw more current and output not stable

feng tang

Part Number: TPS62130A

We use TPS62130A to convert the voltage from 2.8V to 5V, the circuit are exactly same as TPS62130A_EVM, but it draw more current 10.8mA with 10mF load and output voltage keep jumping from 4.6V to 4.9V, any one have idea what is going on?

Thanks,

Feng,

Can you clarify your request? You state you are converting 2.8 V to 5 V. That is not possible TPS62130A is a buck converter only. You state that the circuit is exactly the same as the EVM. The EVM is designed to convert an input voltage in the range of 3.7 V to 17 V to a regulated output of 3.3 V.
