LT3470AIDDB#TRMPBF application field and working principle

The LT3470AIDDB#TRMPBF is a family of DC-DC switching regulators designed to deliver high power at low cost and low external component count. Its low-noise bidirectional operation and low quiescent current make it ideal for powering any application requiring a high efficiency, low noise voltage regulator.The LT3470AIDDB#TRMPBF is a highly efficient DC-DC switching regulator that operates over a wide input voltage range of 4.5V to 27V and provides an adjustable output voltage from 0.8V to 24V. It is capable of delivering up to 3A output current and has an operating efficiency of up to 93% to keep voltage losses to a minimum.The LT3470AIDDB#TRMPBF also includes several integrated protective features including short circuit protection, under voltage protection, thermal shutdown and thermal protection. This regulator is housed in a lead (Pb)-free package, compliant with RoHS standards, making it an ideal solution for any application requiring a cost effective, low-noise voltage regulator.The LT3470AIDDB#TRMPBF is a monolithic switching regulator designed to independently regulate both positive and negative power supplies. The LT3470AIDDB#TRMPBF is capable of step-up, step-down, and inverting buck-boost operation that eliminates external Schottky diodes and optimizes board space while minimizing input/output ripple and switching losses. The versatile internal topology allows for single supply operation and adaptive frequency control that accounts for both the input voltage and output current.The LT3470AIDDB#TRMPBF features an internal NPN transistor for current-mode control, providing fast transient response and loop compensation. The operating frequency can be adjusted with an external resistor, or can be programmed via the frequency select pin. The LT3470AIDDB#TRMPBF is also capable of delivering up to 3A of continuous output current and up to 5A of peak output current.The LT3470AIDDB#TRMPBF is the ideal solution for applications requiring a high efficiency, low noise voltage regulator such as DC motor controls, LED lighting, and portable medical devices. Its low quiescent current and bidirectional operation make it especially well-suited for applications with infrequent change of power loads, thus optimizing efficiency and battery life.In addition, the LT3470AIDDB#TRMPBF provides a wide range of short-circuit protection, under voltage protection, thermal shutdown, and thermal protection making it suitable for applications requiring robust protection against possible fault conditions. With its high efficiency, low noise, and versatile internal topology, the LT3470AIDDB#TRMPBF is the perfect solution for any application requiring a reliable, low cost, and low power voltage regulator.
