The LTC3370 is a highly flexible multioutput power supply IC. The device includes four synchronous buck converters, configured to share eight 1A power stages, each of which is powered from independent 2.25V to 5.5V inputs.The DC/DCs are assigned to one of eight power configurations via pin programmable C1-C3 pins. The common buck switching frequency may be programmed with an external resistor, synchronized to an external oscillator, or set to a default internal 2MHz clock.The operating mode for all DC/DCs may be programmed via the PLL/MODE pin for Burst Mode or forced continuous mode operation. A PGOODALL output indicates when all enabled DC/DCs are within a specified percentage of their final output value.To reduce input noise, the buck converters are phased in 90° steps. Precision enable pin thresholds facilitate reliable power-up sequencing. The LTC3370 is available in a 32-lead 5mm × 5mm QFN package.

Demonstration circuit 2311A is a 4-output power supply featuring the LTC®3370. The LTC3370 has four current mode synchronous buck regulators which can be configured to share eight individual 1A power stages to create one of eight combinations of 1A, 2A, 3A and 4A regulators. The DC2311A is set up as four 2A buck regulators but can be modified to one of the other seven configurations. The input range of the LTC3370 is ideal for single cell Li-Ion/Polymer battery applications. The buck regulators are enabled via external precision threshold enable pins to allow hardwired power up sequences. Performance Summary The LTC3370 has a default operating frequency of 2MHz but can be set between 1MHz to 3MHz using an external resistor. The LTC3370 also has a PLL/MODE pin which allows the internal oscillator to synchronize to an external clock from 1MHz to 3MHz or configure the regulators to forced continuous mode or burst mode. Refer to the LTC3370 data sheet for more details on the electrical and timing specifications.
