TPS65233: AISG Power Source

Sudarshan KR

Part Number: TPS65233
Other Parts Discussed in Thread: LM34936

Hi,

For LNB Power management TPS65233 can be used to get a voltage of either 13V or 18V. For meeting AISG Application requirement range between 10V to 30V are there any suitable devices from TI

Hi,

From the Spec point of view this looks OK. But our requirement is 30V or 10V output which can cater to 2W load. This will gives us around 67mA if 30V is the output and 200mA for 10V Output. Since this device is around 6A, can we get a lower power rated device

Hi, Sudarshan

Why do you say this device is 6A??

For my understanding, it is controller, the power rated is decided by external MOSFET.

BTW, this part doesn't belong to our product line, suggest you post a new question on E2E and label as LM34936 .
