This document introduces the features and characteristics of the XC6401 series products. The XC6401 series products are a 2chVR that can be voltage converted by external control and only use a single load capacitance (CL). In addition, compared to when any one of EN1 or EN2 is in working mode, the operating current (ISS) is approximately 2 times (about 50uA).
The document provides an overview of the XC6401 series voltage converter used in portable devices. It describes the operating principle, how EN1 and EN2 control the output voltage for standby and working modes, and the low‑noise, current‑limit characteristics.
Key sections include the features of the converter, recommended external capacitors, typical performance graphs, and a detailed circuit diagram. The manual also gives typical values for output voltage, current limits, and standby current consumption. This manual is written in Chinese.
| Output voltage VOUT1 | 3.3 V |
|---|---|
| Output voltage VOUT2 | 2.8 V |
| Maximum output current | 300 mA |
| Standby current (ISS) | ~50 µA |
| Input voltage VIN | 4.0 V |
| Input capacitor CIN | 1 µF (ceramic) |
| Load capacitor CL | 1 µF (ceramic) |
Apply a high level ("H") to either EN1 or EN2; the converter will output VOUT1 (3.3 V) or VOUT2 (2.8 V) accordingly.
The standby current (ISS) is approximately 50 µA.
Use 1 µF ceramic capacitors for both the input (CIN) and the load (CL).
