LTC1929IG#TRPBF is a product of Linear Technology, used as an integrated DC DC switching controller for low-noise high-frequency synchronous buck operation. This type of DC DC switching controller is part of a family of high-performance voltage regulators called PMIC - Voltage Regulators - DC DC Switching Controllers.

The LTC1929IG#TRPBF is comprised of two auxiliary outputs, a 3V to 42V input voltage range and can draw up to 1A of output current. It is operated by a precision integrated 0.6V reference. This synchronous step-down (buck) controller is designed to enable maximum efficiency while providing excellent line and load regulation over wide input and output voltage ranges. It also offers a high degree of power supply design flexibility.

In addition to the built-in voltage reference, the LTC1929IG#TRPBF provides over-voltage lockout, under-voltage lockout, soft-start and cycle-by-cycle current limiting. The integrated MOSFET gate driver has a low-impedance output with adjustable deadtime providing optimized performance. The switching frequency is adjustable from 300kHz to 1MHz, allowing the user to generate the most efficient design for their application.

The LTC1929IG#TRPBF is perfectly suited for data communication applications and point-of-load (POL) buck converters, and for powering the internal core logic and peripheral ASICs, FPGAs and microcontrollers. This DC DC switching controller can also be used in motor drives, hot-swap applications, telecom systems, and laptop and notebook power supplies as well as power requirements regulated by adjustable/programmable output voltage.

The LTC1929IG#TRPBF is a highly efficient and reliable current-mode DC DC switching controller with a simple, low-cost control architecture. It operates with a minimum external component count and provides a high level of accuracy and flexibility for applications that require a wide input voltage range and precision output regulation over output voltages from 0.5V to 6V.

The switching frequency can be easily adjusted and an internal pulse frequency modulation (PFM) circuit ensures low-noise operation at light loads. The LTC1929IG#TRPBF can outlast a vast range of temperature, humidity, vibration and environmental shocks. The product has a 5-lead SOT-23 package option, making it suitable for a wide range of industrial and commercial applications.

The LTC1929IG#TRPBF is a great choice for engineers who want to get the most out of their DC DC switching controller and applications. The product’s features, reliability, and flexibility make it one of the most valuable voltage regulators in the PMIC - Voltage Regulators - DC DC Switching Controllers family.
