Hi
A customer is evaluating TLV62084A
Engineer found difficulty to benchmark the switching frequency as the measured result does not tally with webench and the needed parameter does not include in datasheet
Test Condition: Vin = 5V, Vout=1.8V Iout=1.1A,
Webench report shows Fsw=2.82MHz
Webench Simulation (Steady State) shows average Fsw=2.344MHz
Bench test on customer board = 2.069MHz
Questions
1. Could you explain the webench result discrepancy 2.82MHz vs 2.344MHz? Which parameter should be taken as reference?
2. Could you provide the chart with Vin 5V, Vout 1.8V / 0A - 2A (similar to Fig8 in the datasheet) ?
3. What is the expected Fsw tolerance (assume fix load @ 1.1A) ?
