- Page 13 LGA110-EVAL-KIT OPERATION Power Up/Down Sequence 1. Please make sure the OUTPUT ENABLE toggle switch (S201) is disabled. 2. Connect the input and output cables to the bus-bars. a. Vin1 and Vin2 connect to the main DC source b. Vo1, Vo2 and Vo3 connect to the E-load c.
- Page 14 LGA110-EVAL-KIT OPERATION Power Up/Down Sequence Con’t 3. If I2C communication is needed, connect I2C dongle to I2C connector (J204 or J206). 4. Select the suitable voltage for Vo1, Vo2 and Vo3 by switches (S601, S602, S603 & S604). Default setting is Pin2 on and the Vout=1V.
- Page 15 LGA110-EVAL-KIT OPERATION Additional information 1. EN1, EN2 and EN3 can control Vo1, Vo2 and Vo3 individually. 2. This demo board is designed to have two LGA110D modules which can be tested efficiency independently. If the user wants to use only one module, need to follow below steps to measure the efficiency. For module1 (2phase 2output) efficiency measurement: 1.
