LT3471EDD#PBF Description

Short technical summary and product information.

The LT3471EDD#PBF is a versatile dual switching regulator IC from Analog Devices, designed for boost and inverting applications. It integrates two 42V, 1.3A switches, enabling high output voltages up to 40V and supporting both positive and negative dual rail outputs. The device operates with a wide input voltage range from 2.4V to 16V and features a high switching frequency of 1.2MHz, allowing for the use of small, low-profile external components.

 

This regulator is ideal for applications requiring compact power solutions, such as organic LED power supplies, digital cameras, white LED backlighting, and cellular phones. Its ability to configure as two boosts, a boost and an inverter, or two inverters provides design flexibility. The LT3471EDD#PBF is housed in a low-profile 10-lead 3mm x 3mm DFN package, suitable for space-constrained designs.

 

Key electrical characteristics include a low switch VCESAT of 330mV at 1.3A and a low shutdown current of less than 1μA. The device utilizes a constant frequency current mode PWM architecture for predictable output noise. The adjustable output type and boost/SEPIC topology make it adaptable to various power requirements.
