PIN DESCRIPTION

PIN # 1( -IN) and PIN # 3 (+IN): Input Voltage to the unit. Input Voltage Range; +/-10% Vi, nom.

PIN # 2 (SHDN): Will shut down the output when pulled to (-IN).

PIN # 4 (+OUT) and PIN # 6 (-OUT): Unit Output Voltage.

PIN # 5 (COM): Is a Center Tap between (+OUT) and (-OUT) and could be used as a common output pin for Dual Output Bipolar Operation.

REMOTE SHUTDOWN: The converter is turned off when Pin # 2 (SHDN) is clamped to Pin # 1 (-IN) within less than 0.4V.

NON-ISOLATED SHUTDOWN

ISOLATED SHUTDOWN

SINGLE/DUAL OUTPUT OPERATION: The converter can be operated as a single output source of nominal Vout with a load connected between (-Out) and (+Out) or as a dual bipolar source with loads connected between (-Out) and (Com); and (+Out) and (Com) with each load being powered at Vout/2.
