8.2.1.2 Detailed Design Procedure
8.2.1.2.1
Custom Design With WEBENCH® Tools
Click here to create a custom design using the LM25183 -Q1 device with WEBENCH® Power Designer.
1. Start by entering the input voltage (VIN), output voltage (VOUT), and output current (IOUT) requirements.
2. Optimize the design for key parameters such as efficiency, footprint, and cost using the optimizer dial.
3. Compare the generated design with other possible solutions from Texas Instruments.
The WEBENCH Power Designer provides a customized schematic along with a list of materials with real-time
pricing and component availability.
In most cases, these actions are available:
Run electrical simulations to see important waveforms and circuit performance
Run thermal simulations to understand board thermal performance
Export customized schematic and layout into popular CAD formats
Print PDF reports for the design, and share the design with colleagues
Get more information about WEBENCH tools at www.ti.com/WEBENCH.
8.2.1.2.2
Custom Design With Excel Quickstart Tool
Select components based on the converter specifications using the LM25183-Q1 quick-start calculator.
8.2.1.2.3
Flyback Transformer – T1
Choose a turns ratio of 1 : 1 based on an approximate 70% max duty cycle at minimum input voltage using
Equation 14, rounding up or down as needed. While the maximum duty cycle can approach 80% if needed a
particularly wide input voltage application, it increases the peak current stress of the secondary-side components.
(14)
Select a magnetizing inductance based on the minimum off-time constraint using Equation 15. Choose a value of
12.5 µH to allow some margin for this application. Specify a saturation current of 3 A, above the maximum switch
current specification of the LM25183 -Q1.
(15)
Note that a higher magnetizing inductance provides a larger operating range for BCM and FFM, but the leakage
inductance can increase based on a higher number of primary turns, NP. Equation 16 and Equation 17 give the
primary and secondary winding RMS currents, respectively.
(16)
(17)
Find the maximum output current for a given turns ratio using Equation 18, where the typical value for ISW-PEAK is
the 2.5-A switch peak current threshold. Iterate by increasing the turns ratio if the output current capability is too
low at minimum input voltage, checking that the SW voltage rating of 65 V is not exceeded at maximum input
voltage.
