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 VOUT2 whose maximum output current decreases accordingly. Derating is necessary for certain VIN, VOUT and thermal conditions.

Demonstration circuit 1368A exercises four adjustable linear regulators in parallel using the LT3080-1, which incorporates an internal ballast resistor. The ballast resistor allows direct paralleling of devices without the need for PC board resistors or sensor resistors.The paralleled devices provide up to 4.4A of output current at 1.2V. Architected as a precision current source and voltage follower, the LT3080-1 can be used in many applications requiring high current, adjustability to zero output, and no heat sink. The device brings out the collector of the pass transistor to allow low dropout operation when used with multiple supplies. The LT3080-1's output voltage can be programmed to any level between 0V and 36V; however the demo board has a reduced input voltage range from 1.7V to 25V due to the input capacitor voltage rating.

The LTC3803 is a constant frequency current mode flyback controller optimized for driving N-channel MOSFETs in high input voltage applications. Constant frequency operation is maintained down to very light loads, resulting in less low frequency noise generation over a wide range of load currents. Slope compensation can be programmed with an external resistor.The LTC3803 provides ?1.5% output voltage accuracy and consumes only 240?A of quiescent current. Ground-referenced current sensing allows LTC3803-based converters to accept input supplies beyond the LTC3803?s absolute maximum VCC. A micropower hysteretic start-up feature allows efficient operation at high input voltages. For simplicity, the LTC3803 can also be powered from a high VIN through a resistor, due to its internal shunt regulator. An internal undervoltage lockout shuts down the LTC3803 when the input voltage is too low to provide sufficient gate drive to the external MOSFET.The LTC3803 is available in a low profile (1mm) 6-lead SOT-23 (ThinSOT?) package.
