The LTC3374AEUHF#PBF is a high-accuracy, 8-channel parallelable 1A buck DC-DC converter housed in a 38-pin QFN package. This multi-output power supply IC integrates eight synchronous 1A buck converters, each powered by independent 2.25V to 5.5V input supplies. It offers improved efficiency and output voltage accuracy compared to previous versions, along with an added overvoltage (OV) indicator.
The converters can be used independently or in parallel to achieve higher output currents up to 4A using a shared inductor. The switching frequency can be programmed externally, synchronized to an external oscillator, or set to a default internal 2MHz clock. The operating mode for all converters is programmable via the MODE pin. To minimize input noise, the buck converters are phased in 90° steps. Precision enable pin thresholds facilitate power-up sequencing.
This DC-DC converter is suitable for general-purpose multichannel power supplies. Its master-slave configurability allows for up to 4A of output current with a single inductor. The device features ±1% VFB accuracy for buck 1 and ±1% PGOOD accuracy. It operates within a temperature range of -40℃ to 125℃.
Each of the 8 outputs can provide up to 1A of current.
The input voltage range is from 2.25V to 5.5V.
The output voltage can be set from 0.8V to 5.5V.
The operating temperature range is -40℃ to 125℃.
It is supplied in a 38-pin QFN package suitable for surface mounting.
The RoHS status is listed as RoHS3 Compliant.
The Moisture Sensitivity Level is 1 Unlimited.
