Introduction

AI Translation

The LTC3374 is a high efficiency multioutput power supply IC. The DC/DCs consist of eight synchronous buck converters (1A each) all powered from independent 2.25V to 5.5 V input supplies. The DC/DCs may be used independently or in parallel to achieve higher currents of up to 4A per output with a shared inductor. 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 MODE pin. To reduce input noise the buck converters are phased in 90° steps. Precision enable pin thresholds provide reliable power-up sequencing. The LTC3374 is available in a compact 38-lead 5mm × 7mm QFN package as well as a 38-lead TSSOP package.
