The LTC3374AEUHF#TRPBF is an integrated multi-channel, multi-topology, high efficiency and low quiescent current DC-DC switching regulator. It is an advanced power management solution ideal for industrial and consumer applications. This microcontroller-based DC-DC regulator integrates both synchronous and asynchronous buck as well as boost channels in one device. This enables designers to design single-sided and multi-sided systems capable of providing optimal power conversion for a wide range of applications ranging from notebook computers to industrial and consumer applications.

The LTC3374AEUHF#TRPBF application field includes, but is not limited to, powering industrial process controllers, motion control systems, automotive systems, consumer electronics, medical equipment and robotic systems. By utilizing its wide input voltage range, the device helps designers achieve maximum design flexibility and improved overall system efficiency. Its high frequency operation, multiple programmable frequency range, 12V and 28V voltage sensing and software-programmable under-voltage protection provide a low risk solution for industrial, medical, and automotive applications.

As one of Linear Technology’s most advanced DC-DC switching regulators, the LTC3374AEUHF#TRPBF is based on a Regulated Current working architecture. This architecture enables the device to perform continuous conduction mode (CCM) operation, important for low output voltage applications. The Regulated current mode allows the user to independently program the switching frequency and the inductor current limit. This feature allows the user to optimize system performance, minimize the output ripple, and improve overall system efficiency.

The DC-DC regulator also includes an advanced hardware protection feature. It has a built-in over-temperature, under-voltage lockout, and over-current protection designed for industrial applications. The built-in overcurrent protection monitors the output voltage and current to protect the system from sudden surges, shorts and overloads.

The LTC3374AEUHF#TRPBF switching regulators also offer maximum power conversion efficiency and very low quiescent current through its advanced power management system. It supports multiple step-down and step-up configurations and offers programmable current limit and voltage tracking at the input and output. This regulator provides a high level of current accuracy, which is ideal for applications requiring low-power control or low-noise operation.

The LTC3374AEUHF#TRPBF offers superior power conversion performance, low noise and high efficiency operation. It also provides a high level of integration with an integrated controller core, power MOSFETs, protection circuitry, monitoring circuitry and internal EEPROM memory. This feature-packed DC-DC regulator is offered in an ultra-small, low-profile 4.5mm2 QFN package, which makes it an ideal choice for space-constrained applications.
