The E-L5972D013TR is a DC-DC switching regulator that provides integrated power conversion solutions for power management applications. It can provide dc-dc The output is intended for battery powered, or general-purpose applications such as point-of-load (POL) power supplies. The E-L5972D013TR is packaged in a space saving 2 x 2.5mm, 24-lead, thermally enhanced QFN package that reduces the board area required for system design.
Application Field
The E-L5972D013TR DC-DC switching regulator is mainly applied to various high-current or low-voltage power management applications, including mobile, automotive and industrial systems. These fields are:
- Industrial Automation
- Automotive
- Networking and Telecommunications
- Medical Equipment
- Consumer Electronics
- Battery-Powered Devices
In each of these fields, the E-L5972D013TR offers a wide range of solutions for applications such as 5V-to-3.3V regulation, 3V-to-1.8V regulation and 12V-to-5V regulation.
Working Principle
The E-L5972D013TR DC-DC switching regulator is based on a DC-DC buck-boost architecture, which combines a buck converter and a boost converter to provide an adjustable output voltage. The device is designed to provide a regulated output voltage over different line and load conditions. The buck-boost topology of the E-L5972D013TR allows it to accept an input power range from 2.5V to 26V and regulates the output voltage from 0.9V to 5.5V.
The E-L5972D013TR features a low-side MOSFET with a dedicated Pulse Width Modulation (PWM) controller and integrated switching power stage to achieve high-efficiency, high-frequency conversion. The device integrates an internal high current low dropout linear regulator and runs in a high efficiency, low noise pulse width modulation (PWM) mode with a 1.3MHz fixed frequency. The high frequency PWM switching allows for fast loop response and allows use of small external components.
The E-L5972D013TR offers a package of solutions that provide design flexibility and high efficiency. The device integrates several features such as programmable soft-start, adjustable frequency, and over current protection that help the designer to build a safe and reliable power system.
