The TPS92023D is a high-current, high-efficiency, 100-V integrated synchronous boost converter for powering LEDs from a single cell Lithium-ion battery. It is usually employed in applications such as LED flashlights, LED signs and displays, LED exit signs, and LED Torchlights. Its integrated control logic ensures the LEDs remain constantly lit and operate in the most efficient way.

The TPS92023D is designed with a high-current, low-voltage, voltage-mode boost converter capable of delivering up to 25A of peak current. The 100V input voltage rating of the controller provides the necessary safety margin when driving high powered LED applications. The controller is also capable of operating with input voltages as low as 0.5V. The high input voltage range of the controller prevents it from being overpressed by the input voltage and thus prevents damage to the LED circuits.

The TPS92023D has a unique sensing circuit, which allows it to detect the LED current accurately. This sensing circuit is calibrated to ensure the LEDs are driven to their optimal efficiency level. This feature helps reduce the Total Harmonic Distortion (THD) by ensuring that the LED currents are accurately controlled. The TPS92023D automatically adjusts the LED current according to the detected LED voltage to ensure maximum efficiency and optimum LED brightness.

The TPS92023D also integrates an over-temperature protection (OTP) feature which saves the LEDs from burning out if the operating temperature increases beyond the maximum operating temperature. This feature helps to protect and prolong the life of the LED devices.

The TPS92023D employs a low-current architecture design that eliminates the need for additional external components. This feature eliminates the risk of device overload or over-temperature, which can cause a device failure. The TPS92023D also integrates an internal thermal-shutoff feature, which shuts down the device if it detects a temperature rise beyond the maximum limit. This feature helps protect the device and the LED devices from burning out.

The TPS92023D has an adjustable frequency control feature that operates in both Sine and Square waveforms. This ensures that the LED have optimal efficiency while still maintaining excellent light output. The frequency of the Square waveform is adjustable from 1kHz to 20kHz and the frequency of the Sine waveform is adjustable from 100Hz to 1MHz. The adjustable frequency control feature also helps prevent any interference issues between the LED driver and other electronic devices in the vicinity.

The TPS92023D is designed for easy integration into a variety of LED lighting systems. Its integrated control logic and protection features make the TPS92023D ideal for powering LED displays, LED lights, LED signs, LED torches and more. Its fast switching frequency and low-current architecture make it an ideal choice for a wide range of LED applications.
