TIDA-00122: UCD 8220 and MSP430 design question

Tommy Tzeng

Part Number: TIDA-00122

Dear Sir,

i have a customer that need to convert from DC voltage 12v to AC voltage AC110V_total watts 100w~150w(60 Hz sinewave) inverter application. the reference design about TIDA-00122 can i ask a few questions?

1.do you have a MSP430G2330 source code? for TIDA-00122 reference design.

2.do you have a datasheet for transformers(T1_EI33 12PIN BOBIN)?

3.if changing the input voltage from 12v to 24v i need to change which components or parameters?

Hi Sandeep Tallada,

Do you have L2 (EE2005：Boost Inductor, EE20 6 Pin Vertical) datasheet?

I checked but I could not find details on L2 inductor. As far as I remember we tested this as a square wave AC output thus L2 was shorted. L2 is needed if customer is looking for quasi sine wave AC output.
