The RT6337 family are high efficiency synchronous step-down DC-DC converters with pseudo constant switching frequency 500kHz and deliver up to 9A output current. The RT6337A/B and RT6337AH/BH operate from 4.5V to 23V input voltage. The output voltage of RT6337A/AH is programmed between 0.6V to 5.5V and RT6337B/BH is fixed to 3.3V output voltage. The input voltage of RT6337C/CH ranges from 5.2V to 23V and the output voltage of RT6337C/CH is fixed to 5.1V.<br /><br />The RT6337 adopts Advanced Constant On-Time (ACOT<sup>®</sup>) control architecture that provides ultra-fast transient response and further reduces the external component count. In steady states, the ACOT<sup>®</sup> operates at nearly constant switching frequency over line, load and output voltage ranges and makes the EMI filter design easier.<br /><br />By setting the voltage of the EN/MODE pin, RT6337 operates either in diode emulation mode (DEM) or ultrasonic mode (USM) at light load. The USM maintains operation frequency above 25kHz, which eliminates the acoustic noise. In the DEM, RT6337 provides the best light-load efficiency and improves the acoustic noise with spread spectrum function.<br /><br />RT6337 provides PGOOD indicator for easy system sequence control. Full protection features are also integrated in the device, including the cycle-by-cycle current limit, OVP, UVP, input UVLO and OTP.<br /><br />All above functions are integrated in a UQFN-23L 3x3 (FC) package.
