A. The areas under the curves represent conditions that may cause the device to oscillate. For curves B, C, and D, R2 and V+ are adjusted to establish the initial VKA and IKA conditions, with CL = 0. VBATT and CL then are adjusted to determine the ranges of stability. Figure 15. Copyright © 1991–2007, Texas Instruments Incorporated Submit Documentation Feedback 11 Product Folder Link(s): TL1431 |
