PRODUCTION DATA
Choosing a switching frequency has a trade off between efficiency and bandwidth. Higher switching frequencies will have larger bandwidth, but a lower efficiency than lower switching frequencies. A switching frequency of 215 kHz was chosen as a trade off between bandwidth and efficiency. Using Equation 2 for the UC1825B-SP, RT and CT were chosen to be 10 kΩ and 680 pF, respectively.
