1.2 Modification

The EVM is designed to support some modifications by the user. The external components can be changed according to the real application.

The C6 is reserved for one cell super-capacitor, of which the voltage is normally from 1.2 V to 2.7 V. One typical application of the TLV61048 is to generate 12-V output from one cell super-capacitor. In such application, the VIN pin of TLV61048 should be powered by a typical 3.3-V external power supply.

To reduce the output ripple during stable and load transient condition, the C4 and C5 can be populated to increase the output capacitor.

The feed-forward capacitor C8 can help to improve the response performance and the phase margin if the value is properly selected. Refer to this application note to select the feed-forward capacitor if required. Feedforward Capacitor Makes Boost Converter Fast and Stable.
