DESCRIPTION
Demonstration circuit 1367A features the LTM
triple output μModule
mode outputs and one LDO output. Each LTM4615 DC/DC
converter has a separate input and enable pin. The LTM4615
maximum load current is 4A for each switch mode channel
and 1.5A for the VLDO™ channel. However the DC1367A
is configured with the LDO input supply connected to
the VOUT2 whose maximum output current decreases
accordingly. Derating is necessary for certain V
