The LM5022SEPBLDT/NOPB is a member of Texas Instruments’ family of Switched-Mode Power Supply (SMPS) evaluation boards. This wide range of devices has a whole host of applications, such as in DC-DC motor control, home appliance battery pack charging, and low-voltage AC-DC converters. The LM5022SEPBLDT/NOPB is specifically designed for evaluating switched-mode power supplies that use a synchronous rectification technique.

A basic SMPS circuit consists of an input power source, a switch, a topology, a transformer, a rectifier, and filters. In its simplest form, a switched mode power supply works by taking AC power, rectifying it to DC, and then switching it back to AC with higher frequency. This is done by use of a switch, usually a semiconductor switch such as a MOSFET. As the switch turns on and off very rapidly, it can transmit energy to the output with high efficiency by reducing losses associated with resistive components. By comparing input and output frequencies, the ratio of these signals can be used to control the duty cycle of the switch in order to regulate the output voltage.

The LM5022SEPBLDT/NOPB board enables designers to see SMPS in action and make sure it performs correctly, thanks to its built-in monitoring, fault protection, and protective circuitry. Its power stages consists of a primary boost converter and a secondary bridge converter. The primary boost converter is based on a Synchronous Rectified Buck Oscillator (SRBO) topology, while the secondary bridge converter is based on a Half-Bridge Spike Motor Driver (HMDRIVER) topology. The LM5022SEPBLDT/NOPB evaluation board also provides isolated output for ground loops and output protection.

The LM5022SEPBLDT/NOPB evaluation board is capable of providing both low-voltage and high-voltage power outputs for applications that require output voltages ranging from 0.7V to 24V. It also allows for the testing of both buck-boost and boost-buck type designs for a very wide range of output voltages. The board is equipped with LEDs that provide an indication of the board’s status and a LCD display for displaying the board’s output voltage. The board also has the ability to store settings that can be recalled at power-on, and it provides self-test and fault-protection functions.

Thus, the LM5022SEPBLDT/NOPB evaluation board is an invaluable tool for evaluating SMPS designs. It enables designers to quickly test different configurations of switching frequencies, ranges of output voltages, and output protections. With this device, designers can quickly test the performance of their power supplies and make sure that they meet the specifications of their intended application.
