Demonstration circuit 2419A features the LTC®3372 in a multi-output step-down converter. The controller portion of the LTC3372 drives a high output voltage (HV) buck converter which has an input voltage range of 6V to 60V.Its output voltage (VOUT_HV) is nominally 5V but can be configured for either 5V or 3.3V with the VOUTPRG pin. VOUT_HV supplies power to the configurable buck regulator. This regulator provides four low voltage (LV) outputs labelled VOUT1-4. These outputs are 1.2V/2A, 1.8V/2A, 2.5V/2A and 3.3V/2A respectively. When VOUT_HV is configured for 5V, it can supply 6A to the external loads with full load on VOUT1-4. With no load on VOUT1-4, VOUT_HV can supply 10A to the external loads. See Figure 3 for the Block Diagram.
