Figure 1 TPS54394 internal structure diagram
The TPS2394 is a 3A/3A dual synchronous step-down (buck) converter with two integrated N-channel MOSFETs for each channel. It operates using D-CAP2TM control mode. The fast transient response of D-CAP2TM control reduces the required output Capable to meet a specific level of performance. Proprietary internal circuitry allows the use of low ESR output capacitors including ceramic and special polymer types.
