Product Details

Demo circuit 3204A features the LTC3314A, 5V, dual 4A/dual-phase 8A step-down DC/DC regulator IC. This demo circuit is configured as a 2MHz, 3.3V input buck regulator with dual 4A output at 1.2V and 1.8V.

The LTC3314A features dual monolithic synchronous 4A step-down power stages in a 30-ball, 2.2mm × 2.7mm WLCSP package for space saving applications with demanding performance requirements. Both bucks achieve high efficiency and fast transient response with small external components. The LTC3314A can also be configured as a single output, dual-phase 8A step-down converter. Please refer to DC3205A as a single output dual-phase application example. The LTC3314A data sheet gives a complete description of its operation and application information. The data sheet must be read in conjunction with the demo manual when evaluating or modifying this demo circuit.

DC3204A supports three operation modes, including pulse-skipping, forced continuous and Burst Mode® operation. The clock frequency and the operation mode are shared by both regulators. User can select desired operation mode with JP3 jumper. Setting JP3 to FC/SYNC position also allows the LTC3314A to sync to a clock frequency from 1MHz to 3MHz, operating in forced continuous mode.

An EMI filter is included in this demo circuit for noise sensitive applications. To power with EMI filter, please apply input voltage via VIN EMI terminal.
