<!-- Paste General Description --><p align="justify">The RTQ2158 is a high-performance, Advanced Constant On-Time (ACOT<sup>®</sup>) monolithic synchronous step-down DC-DC converter that can deliver up to 8A output current from a 2.85V to 6.5V input supply. The device integrates low R<sub>DS(ON)</sub> power MOSFETs, accurate 0.6V reference and an integrated diode of bootstrap circuit to offer a very compact solution. </p><p align="justify">The RTQ2158 adopts Advanced Constant On-Time (ACOT<sup>®</sup>) control architecture that provides ultrafast transient response and further reduces the external-component count. In steady states, the ACOT<sup>®</sup> operates in nearly constant switching frequency over line, load and output voltage ranges and makes the EMI filter design easier. </p><p align="justify">The device offers independent enable control input pin and power good indicator for easily sequence control. To control the inrush current during the startup, the device provides a programmable soft-start up by an external capacitor connected to the SS pin. Fully protection features are also integrated in the device including the cycle-by-cycle current limit control, UVP, input UVLO and OTP. The RTQ2158-QA is available in a thermally enhanced WET-WQFN-21L 4x4 (FC) package.</p>
