1. General Description

The RTQ2117A provides the electrical signatures on D+/D- to support charging schemes compatible with the USB 2.0 Battery Charging Specification BC1.2 and Chinese Telecommunication Industry Standard YD/T 1591-2009. Auto-detect mode is also integrated which supports USB 2.0 Battery Charging Specification BC1.2 Dedicated Charging Port (DCP), Divider 3 mode and 1.2V shorted mode to comply with the legacy fast charging mode of mobile devices. The high bandwidth data switch is implemented in the RTQ2117A. The RTQ2117A integrates a high efficiency, monolithic synchronous buck converter that can deliver up to 3A output current from a 3V to 36V wide range input supply and is protected from load-dump transients up to 42V.

2. Performance Specification Summary

The Automotive HV-Buck conveter has an input voltage range from 3V to 36V, and the output voltage is 5V. It can operate in forced PWM mode and PSM mode. And the current limit is implemented by RLIM for difference application. The RTQ2117A is available in a WETD-VQFN-32L 5x5 package. Table 1.

3. Power-up Procedure

1. Connect input voltage (3V < VIN < 36V) to the VIN pin. 2. Setting MODE and RLIM for device request. 3. To enable Buck converter by the external EN pin. 4. To connect an external load to output and verify the output voltage versus applied current.

4. Output Voltage Setting

The output voltage set by external feedback resistors expressed in the following equation. <a class="fancybox" href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq2117agqvt-qa/html-images/image001_en.png"><img width="144" height="46" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq2117agqvt-qa/html-images/image001_en.png" alt="Technical Document Image Preview" /></a> where the reference voltage VFB is 0.8V (typical). The placement of the resistive divider should be as close as possible to the FB pin. For better output voltage accuracy, the divider resistors with ±1% tolerance or better should be used. The resistance of R2 is not larger than 170kΩ for noise immunity considerationis recommended .

The capacitance values of the input and output capacitors will influence the input and output voltage ripple. 2. MLCC capacitors have degrading capacitance at DC bias voltage, and especially smaller size MLCC capacitors will have much lower capacitance.
