Mingjiada Supply ADI LTC3374 Buck DC/DC Converters, Supply Multioutput Power Supply IC

With the growing demand for multiple low-voltage power rails in FPGAs, SoCs, in-vehicle infotainment systems and industrial control equipment, the limitations of traditional discrete power supply solutions in terms of PCB area, BOM cost and design complexity are becoming increasingly apparent. Mingjiada Electronics, as a specialist electronic component supply chain service provider, has long supplied the LTC3374 multi-output power IC from ADI (Analog Devices) – a highly integrated 8-channel, 1A synchronous step-down DC/DC converter that provides a compact, flexible and reliable solution for multi-rail power systems.

[ADI] LTC3374A – High-accuracy, 8-channel, parallelable 1A step-down DC/DC converter
The LTC3374A is a multi-output power supply IC comprising eight synchronous 1A step-down converters, each powered by an independent 2.25V to 5.5V input supply. The LTC3374A is a pin-compatible upgrade to the LTC3374, offering higher efficiency, improved output voltage accuracy and the addition of an over-voltage (OV) indicator. To minimise input noise, the buck converters are phase-shifted in 90° steps. A precise enable pin threshold simplifies power-up sequencing. The LTC3374A is available in a compact 38-pin 5mm x 7mm QFN package and a 38-pin exposed pad TSSOP package.
