Product Details

Demonstration circuit 1367A features the LTM4615EV, a triple output μModule^® regulator consisting of two switch-mode outputs and one LDO output. Each LTM4615 DC/DC converter has a separate input and enable pin. The input supply voltage is 2.5V to 5.5V and the demo board provides outputs of 1.8V @ 4A, 1.2V @ 2.5A and 1V @ 1.5A. The LTM4615's 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 V_OUT2 whose maximum output current decreases accordingly. Derating is necessary for certain V_IN, V_OUT and thermal conditions.
