Introduction

LT3692AIUH#TRPBF is a synchronous buck controller DC/DC converter from Linear Technology. It is designed both to provide accurate current accuracy and precise load regulation over a wide input voltage and load range. The LT3692AIUH#TRPBF is a highly integrated step-down DC/DC converter that combines a high-efficiency, high-side driver and an adjustable compensation control loop. The LT3692AIUH#TRPBF is an ideal choice for applications that require precise current accuracy, superior transient response, and output voltage adjustment over a wide input voltage and load range.

Application Field

The LT3692AIUH#TRPBF is suitable for a wide range of applications including industrial, consumer, audio, computer and other systems. It is a high performance PWM current mode buck regulator, ideal for use in applications requiring precise current accuracy, superior transient response and output voltage adjustment over a wide power supply range. It is suitable for providing both high current and high voltage operation from a single input supply. It is particularly useful in applications that require high accuracy current delivery, such as LED lighting, battery charger/management, and transformerless power supplies.

Working Principle

The LT3692AIUH#TRPBF uses an adjustable compensation control loop and an adjustable error amplifier circuit to accurately control the output voltage. The adjustable compensation control loop provides excellent loop stability over a wide range of input voltages and output currents. The adjustable error amplifier circuit allows the user to precisely set the output voltage to any level between 0V and the input voltage. The LT3692AIUH#TRPBF is equipped with a power-on reset circuit and an adjustable reset threshold, which provides additional protection against output voltage overshoot or undershoot during power-up or power-down. The LT3692AIUH#TRPBF also features built-in soft-start/soft-stop control, pulse-by-pulse current limit, and programmable switching frequency. The built-in soft-start/soft-stop control ensures that the output voltage is ramped up and down smoothly, while the pulse-by-pulse current limit ensures that each switch cycle is protected against short circuit.

Conclusion

The LT3692AIUH#TRPBF is a compact and high performance synchronous buck controller DC/DC converter from Linear Technology. It is designed both to provide accurate current accuracy and precise load regulation over a wide input voltage and load range. The adjustable error amplifier circuit, power-on reset, adjustable reset threshold, and built-in soft-start/soft-stop control provide excellent voltage stability and protection against output voltage overshoot or undershoot. It is suitable for a wide range of applications including industrial, consumer, audio, computer and other systems. Thus, the LT3692AIUH#TRPBF is an ideal choice for applications that require precise current accuracy, superior transient response, and output voltage adjustment over a wide input voltage and load range.
