The LTC3862IFE-1#TRPBF is a high-performance, synchronous DC/DC switching controller intended to drive synchronous buck converters. This product is part of the LTC3862 family of 2-phase and 4-phase Burst Mode controller solutions which are designed to optimize power efficiency from a high +6V supply voltage. It is a perfect solution for those looking to develop active-ripple and zero-ripple converters for telecom, automotive and industrial applications.

The LTC3862IFE-1#TRPBF is capable of operating as a single-phased switching controller for simple power solutions. Its dual-output capability makes it quite versatile, as it can be used to supply multiple power outputs from one regulator. Its wide Phase⇔Phase and Phase⇔Buck current range allows for flexibility and customization of the output voltage. Additionally, the wide input voltage range, precision output voltage regulation and fast response time make this product ideal for portable and distributed low-power applications.

As far as features, the LTC3862IFE-1#TRPBF has a wide operating range of 0.8V to +6V, a wide range of programmable switching frequency, an enable input, and a power good output. Its built-in loop compensation allows for fast transient response even at 10% load change or as low as 0% load change due to its improved load transient performance. Its ripple reduction features enable the controller to control its output ripple ensuring a smooth output for variable loads.

In terms of application fields, the LTC3862IFE-1#TRPBF is used in point of load (POL) power converter solutions, telecommunications equipment, automotive power management solutions, industrial motor drives, and other low-power applications. As it is capable of both power and short circuit protection, it is especially useful for mission-critical applications that require reliable and efficient power solutions. Furthermore, thanks to its AEC-Q100 qualification, it is well-suited for automotive applications.
