LGA50D Evaluation Board User Manual OPERATION Here are the instructions to power up the PCB and modules. Power up sequence To power up and configure the evaluation card, please follow the steps as described below. 1. Initial set position of the enable switch Please make sure the OUTPUT ENABLE toggle switch (S201) is in the “disable”... - Page 8 LGA50D Evaluation Board User Manual 2. Connection and configuration Connect the input and output cables to the M6 terminations of the PCB. Then connect the following: a. Connect the Vin1 and Vin2 connections to the DC power source with a voltage setting in the range of 7.5Vdc to 14Vdc b.

LGA50D Evaluation Board User Manual 6. The Power down sequence To disable the outputs from the evaluation board, please take the following steps: • Toggle Enable switch to disable Vout • Turn off main voltage to Vin1 and Vin2 Note that not following power up/down sequence may damage the evaluation board. Additional information 1. - Page 12 LGA50D Evaluation Board User Manual 2. Enabling each output The outputs of the individual converters can be enabled or disabled by populating and de- populating the enable jumpers as required. Fig. 9 – The enable jumpers – all 3 shown in place to enable all 3 outputs If the enable signal is bouncing during enable and disable, a 0.1uF 0603 capacitor can be added at C211, C212 and C213 for monotonic signal.

Page 13: Test Functions
LGA50D Evaluation Board User Manual Test functions The evaluation board is also equipped with test points to provide easily accessible voltage measurement points. 1. Vin and Vout sense locations Accurate input and output voltage measurements via pin-headers can be found on J205 and J1205. - Page 14 LGA50D Evaluation Board User Manual 2. Ripple and regulation measurement locations There are 3 test points provided to give accurate measurements of the output noise and ripple from the LGA50D. The mating connector to the SMA connector found on the Evaluation board can be defined as “A Straight Cable Mount SMA Connector, Plug, Crimp Termination type RG174U”.
