3.4 Operating the EVM With the Onboard Analog Loop Control Circuit

1. J34 through J37 headers must be closed to activate the onboard analog voltage loop control circuit.
2. To operate the EVM as a regulated voltage source, follow the power up and power down sequence for buck mode or boost mode operation whichever is appropriate.
3. Note that with the circuit breaker MOSFETs employed by the EVM, HVPS should be applied for boost start-up. After the start-up, it can be turned off. Only after the circuit breaker MOSFETs are replaced with a direct short across the breaker will the EVM not require the HV-PS to assist boost start-up.
