Demonstration circuit 1953A is an 8-output power supply featuring the LTC3374. The LTC3374 has eight synchronous buck regulators each with an independent VIN supply. Up to four buck regulators may be paralleled together to create a higher power buck regulator with a single inductor. The input range of the LTC3374 is ideal for single cell Li-Ion/Polymer battery applications. The buck regulators can be enabled via external precision threshold enable pins to allow hardwired power up sequences.
