The RT8088A is a full featured 5.5V, 3A, Constant-On-Time (COT) synchronous step-down converter with two integrated MOSFETs. The current mode COT operation with internal compensation allows the transient response to be optimized over a wide range of loads and output capacitors to efficiently reduce external component count. <br />The RT8088A provides up to 2.7MHz switching frequency to minimize the size of output inductor and capacitors. <br />The output voltage is programmed through an I<sup>2</sup>C interface capable of operating up to 400kHz. The RT8088A is available in the WL-CSP-15B 1.31x2.11 (BSC) package.
