Using the TPS2492/3EVM Hot Swap Controller User's Guide Literature Number: SLUU425A May 2010 – Revised March 2011
User's Guide SLUU425A – May 2010 – Revised March 2011 Using the TPS2492/3 Hot Swap Controller This User’s Guide describes the setup and operation of the TPS2492/3 System Test Board. 1 Introduction This User’s Guide describes the features of the TPS2492/3EVM. The TPS2492/3 schematic, layout and List of Materials are provided. 2 Description The EVM is a 9-V to 80-V module using the TPS2492/3 hot swap controller with external MOSFET.
Description www.ti.com 2.3 Equipment supplied • • 2.4 Equipment Required • • • 2.5 EVM-491 The datasheet and this users guide is available on the TPS2492/3 product page at www.ti.com. Power Supply is able to output twice the steady state current for pulse duration. For the 12-V factory set EVM, steady state power is 25-A nominal. Oscilloscope Current Probe EVM Documentation The manufacturing and engineering documentation for the EVM is shown in sections 3 to 6.
EVM Block Diagram TPS2492EVM-491 2.7.2 www.ti.com dv/dt Control When the VPROG calculates below the 0.4 V minimum, one option is to use dv/dt control to start the uncharged output capacitor. In this way, the power limiting is not used on power up. R11 and C4, (see schematic Figure 2 for component reference), are normally not populated and control the power turn on with a dv/dt soft start. Recommendation for R11 is at 1 kΩ.
