JAJSQK3 November 2023 LM25185-Q1
PRODUCTION DATA
Table 8-1 shows the required input, output, and performance parameters for this application example.
DESIGN PARAMETER | VALUE |
---|---|
Input voltage range | 20 V to 40 V |
Input UVLO thresholds | 19 V on, 18 V off |
Output voltage | 16.4 V |
Rated load current | 1 A |
Output voltage regulation | ±1.5% |
The target full-load efficiency is 89% based on a nominal input voltage of 24 V and an isolated output voltage of 16.4 V. The LM25185-Q1 is chosen to deliver a fixed 16.4-V output voltage set by resistor RFB connected between the SW and FB pins. The input voltage turn-on and turn-off thresholds are established by RUV1 and RUV2. Refer to the LM5185-Q1 Single-Isolated-Output Evaluation Module user's guide for the detailed component list.
