TPS59641RSLT

DC/DC контроллер, архитектура D-CAP+, 3В до 28В, 2 выхода, понижающий, 600кГц, VQFN-48.

The TPS59641RSLT is a 2-channel Step-down Controller with two integrated gate drivers. Advanced control features such as D-CAP+ architecture with overlapping pulse support (undershoot reduction, USR) and overshoot reduction (OSR) provide fast transient response, lowest output capacitance and high efficiency. All of these controllers also support single-phase operation for light loads. The full complement of IMVP-7 I/O is integrated into the controllers including dual PGOOD signals, ALERT and VR_HOT. Adjustable control of VCORE slew rate and voltage positioning round out the IMVP-7 features. In addition, the controllers' CPU channel includes two high-current FET gate drivers to drive high-side and low-side N-channel FETs with exceptionally high speed and low switching loss. The TPS59641 is specifically designed for a VBOOT level of 1.1V.
