The LTC3721EUF-1#PBF is a PMIC (Power Management Integrated Circuit) controller with onboard DC / DC switching controllers to regulate power delivered from one DC source to multiple outputs. It is designed for use in high-frequency, low EMI systems and features short-circuit protection, internal power control, and PWM current-mode control. It is ideal for applications such as LED lighting and systems requiring efficient, high-performance power solutions.

The LTC3721EUF-1#PBF provides an adjustable 2.4V to 6.4V linear regulator output. It also provides an adjustable 0V to V in output voltage. In addition, two separate PWM outputs and two separate synchronous rectified outputs provide adjustable 1.0V to 15V outputs. The outputs are independently programmable using external components.

The LTC3721EUF-1#PBF utilizes a current-mode control architecture to provide both low noise and high accuracy performance. A unique temperature compensation feature allows the current-mode control to maintain efficiency and constant output voltage over a wide input voltage range. Internal soft-start circuitry minimizes inrush current during powerup.

In addition, the LTC3721EUF-1#PBF features short-circuit protection which limits the current in both output channels to a safe level. It also features external power control for both output channels. The PWM outputs are electronically synchronized to provide the lowest possible switching noise and EMI.

The LTC3721EUF-1#PBF is available in a 9.5 x 4.5mm, 0.88mmmax package. It is designed for use in high-power systems and applications requiring multiple power rails. It is well-suited for powering FPGA, ASIC, and SoC designs as well as LED lighting drivers.
