JAJSBO6B June 2012 – May 2019 TPS54678
PRODUCTION DATA.
The TPS54678 uses a transconductance amplifier for the error amplifier and readily supports two of the commonly used frequency compensation circuits. The compensation circuits are shown in Figure 29. The Type 2 circuits are normally implemented in high-bandwidth power supply designs using low ESR output capacitors. In Type 2A, one additional high-frequency pole is added to attenuate high-frequency noise.
The design guidelines for TPS54678 loop compensation are as follows:
