Quick Start Guide
The jumper on Enable pin as shown is in disable mode. When jumper is between
the middle and right pins the signal pin is connected to ground or logic low. When
the jumper is between the left and middle pins, the signal pin is connected to
AVIN or logic High.
WARNING:
evaluation board.
STEP 1:
STEP 2:
Set the “ENA” jumper to the Disable Position. See Figure 2 above.
Set the EN_PB jumper J1 to the desired position. See Figure 3. Pulling
it low disables the pre-bias mode operation. Pulling this jumper high or
letting it float will allow monotonic start-up with a pre-biased output. In
pre-bias mode, VOUT will not discharge very quickly. Therefore, you
may need to apply a small load (~10mA) at shut-down to ensure that
the output voltage discharges. In Figure 3 the jumper is set low to
disable pre-bias mode.
