Product Details

The LTC3375 is a digitally programmable high efficiency multioutput power supply IC. The DC/DCs consist of eight synchronous buck converters (IOUT up to 1A each) all powered from independent 2.25V to 5.5V input supplies.

DC/DC enables, output voltages, operating modes, and phasing may all be independently programmed over I2C or used in standalone mode via simple I/O with power-up defaults. The DC/DCs may be used independently or in parallel to achieve higher output currents of up to 4A per output with a shared inductor. Alarm levels for high die temperature may also be programmed via I2C with a maskable IRQ output for monitoring DC/DC and system faults.

Pushbutton ON/OFF/RESET control, power-on reset, and a watchdog timer provide flexible and reliable power-up sequencing and system monitoring. The LTC3375 is available in a low profile 48-lead 7mm × 7mm QFN package.

Applications
