The ltc3407edd-3#trpbf voltage regulator is a highly efficient, synchronous, step-down DC-DC switching regulator. It is part of the Power Management Integrated Controllers (PMIC) range and part of the Voltage Regulators group, it also belongs to the DC-DC Switching Regulators narrower subgroup. It offers drop-in replacement for existing buck regulator applications and ultra-low component count to reduce bill of materials costs. Designed for very low noise applications, it operates up to 2.25 MHz switching frequency and is capable of driving a 2 A switch from a wide input voltage range. Its flexible architecture allows for two different operating modes, one dedicated to noise-sensitive applications and another devoted to maximizing efficiency. It also can be used in constant frequency (550 kHz, 1.1 MHz, or 2.2 MHz) or variable frequency.

The most common application area for the ltc3407edd-3#trpbf is telecommunications, power generation, automotive, battery-powered systems, industrial process automation and building automation. As it offers high-efficiency rates and low component count, it is well suited to applications that operate from medium to high voltage inputs and require up to medium current.

To understand better its working principle, it is important to explain what is a synchronous buck regulator. A synchronous buck regulator is a switching regulator that have a switchable current path between its input and output, which is driven by an oscillator. When the switch is on, it passes current from the input to the output, and when it is off, it blocks any current flow. The switch is controlled by a signal derived from the oscillator. Synchronous buck converters are required because they offer higher efficiency than non-synchronous buck converters and they can also operate at very low output voltages, making them useful in current regulation applications.

The ltc3407edd-3#trpbf is a synchronous buck converter that has two modes of operation that makes possible to address a wide variety of applications. In current mode operation, it offers fast line and load transient responses, ideal for low-voltage/low-power applications. The frequency mode operation allows for higher frequency operation as well as noise-sensitive applications, achieving very low noise levels when compared to other converters.

The ltc3407edd-3#trpbf offers a wide input voltage range from 4.5 V to 38 V and a dedicated shutdown pin that allows it to operate at very low quiescent current. With its high efficiency levels, the output voltage can be regulated with a pair of resistors. It also offers integrated MOSFET gate drivers, eliminating the need for external gate driver components. As it is optimized for noise sensitive applications, it offers output voltage noise as low as 150 μVRMS.

The ltc3407edd-3#trpbf is an efficient and versatile synchronous, step-down DC-DC switching regulator that offers perfect drop-in replacement for existing buck regulator applications. Its performance and features make it ideal for medium to high voltage and up to medium current applications, particularly noise sensitive ones. Its low component count, efficiency and high output voltage noise levels make it the perfect voltage regulator for a wide variety of applications.
