<!-- Paste General Description --><p align="JUSTIFY"> The RTQ2820A is a high-performance, synchronous step-down converter that can deliver up to 20A output current with a wide input supply voltage range of 3.5V to 17V. The device integrates low R<sub>DS(ON)</sub> power MOSFETs, an accurate 0.6V ± 1% reference over the full operating junction temperature range, and an integrated diode for the bootstrap circuit, offering a very compact solution.<br />The RTQ2820A adopts Advanced Constant-On-Time (ACOT<sup>®</sup>) control architecture that provides excellent transient performance and reduces the count of external components. In steady states, the ACOT<sup>®</sup> can operate at nearly constant switching frequency over line, load and output voltage ranges, making the EMI filter design easier.<br />The device offers a variety of functions to provide more design flexibility. The selectable switching frequency, current limit level, PWM operation modes make the RTQ2820A easy-to-use over wide application range. An independent enable control input pin and power-good indicator are also provided for easy sequence control. The device provides a programmable soft-start-up by an external capacitor connected to the SS/TR pin to control the inrush current during start-up.<br />The RTQ2820A provides complete protection functions including input undervoltage lockout, output undervoltage protection, output overvoltage protection, overcurrent protection, and thermal shutdown. The RTQ2820A is available in a thermally enhanced WQFN-21TL 3x4 (FC) package.<br />The recommended junction temperature range is -40°C to 150°C.</p>
