LTC1702IGN Dual, 550kHz, 2-Phase, Synchronous Step-Down Switching Regulator

The LTC1702IGN is a high-performance dual synchronous step-down switching regulator designed by Linear Technology, now part of Analog Devices. This regulator is tailored for applications demanding high efficiency, compact design, and precise voltage regulation. It is a go-to solution for powering the latest generation of microprocessors and other high-performance digital ICs.

Operating at a fixed frequency of 550kHz, the LTC1702IGN facilitates the use of small inductors and capacitors, leading to a reduction in the overall footprint and size of the power supply. The 2-phase operation significantly reduces the required input and output capacitance and allows for the use of smaller components, saving space and cost on the PCB.

The LTC1702IGN is capable of providing two independently regulated output voltages, which is particularly useful for systems that require different voltage levels for core and peripheral circuits. The outputs are adjustable from 0.8V to VIN, with an output voltage accuracy of ±1%, ensuring precise voltage delivery for sensitive applications.

This regulator includes a range of features that enhance its performance and reliability. It boasts internal top and bottom synchronous power MOSFETs, which provide high efficiency and eliminate the need for external Schottky diodes. The LTC1702IGN also features a phase-lockable fixed frequency from 250kHz to 550kHz, allowing for optimization of efficiency and component size. Furthermore, its No RSENSE™ operation removes the requirement for a current sense resistor, simplifying the design and reducing losses.

Protection features of the LTC1702IGN include overcurrent protection and foldback current limiting, which safeguard the device and the load under extreme conditions. Additionally, it has a soft-start capability that minimizes inrush current during startup, enhancing system stability.

The LTC1702IGN is available in a compact 28-lead SSOP package, making it suitable for space-constrained applications while providing robust power management. Whether for computing systems, telecommunications, or portable electronics, the LTC1702IGN is an excellent choice for designers looking for a reliable and efficient power solution.

With its advanced features and high-performance capabilities, the LTC1702IGN from Linear Technology stands out as a versatile and efficient power management solution for a wide array of electronic devices.
