LT3971IDD-3.3#PBF is a single-channel integrated switch for output current up to 6.4A, step-down DC/DC regulator with adjustable output voltage from 0.6V to 3.3V. It integrates an internal power MOSFET and gate driver, and its operation can be programmed to fixed-frequency, pulse skipping, and low-noise pulse-width modulation (PWM) modes. It features wide operating temperature range and can be used in temperature-critical applications. PMIC - Voltage Regulators - DC DC Switching RegulatorsLT3971IDD-3.3#PBF’s application fields include most of communication, microcontrollers, automotive, audio systems, computers and consumer electronics. It also has been integrated into solutions that require efficient and optimized power supplies.The basic working principle of LT3971IDD-3.3#PBF is quite similar to linear voltage regulators. It prevents excessive output currents that can potentially harm any connected device or system. Its output is regulated by Pulse-Width Modulation (PWM). The voltage is regulated by regulating the duty cycle of this PWM output, which vary depending on the amount of feedback from the output voltage. LT3971IDD-3.3#PBF series are equipped with ultra-low on-resistance internal power MOSFET, which allow for ultra-low output voltage ripple and precise output voltage control, this ensures higher reliability and extremely low EMI noise, extending product life and stability beyond what conventional linear voltage regulatorscan provide.Another great feature of this series is that it has low dropout operation and can track up to 6V and output precise voltage, it can also be configured to power off in extreme cases, prevent devices from damage. LT3971IDD-3.3#PBF also equiped with a power-on reset circuit, which provides power-on reset signal and output disable function. So you don\'t overshoot your output voltage during the startup phase. In addition to this, the LT3971IDD-3.3#PBF series also include a wide variety of built-in protection features such as over-current protection, over-voltage protection, thermal shutdown, under-voltage lockout, over-temperature protection, and short-circuit protection.Its advanced performance and multiple integrated features make the LT3971IDD-3.3#PBF series one of the best power solutions for consumer, automotive and industrial applications with efficient, reliable, high-performance, and low-cost requirement.
