TOREX makeuseXC6401 transform output Voltage Manual
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.

Questions answered in these manuals
What is the maximum output current of the XC6401 regulators?
Each regulator can deliver more than 150 mA, with a 300 mA absolute limit.
Which package types are available for the XC6401 series?
The devices are offered in SOT‑26W, USP‑6B and USP‑6C chip‑scale packages.
How do I switch the output voltage of the XC6401?
Apply a high level ("H") to either EN1 or EN2; the converter will output VOUT1 (3.3 V) or VOUT2 (2.8 V) accordingly.
What is the standby current consumption of the XC6401?
The standby current (ISS) is approximately 50 µA.
What does the EN function do?
The EN function allows the output of each regulator to be turned off independently, greatly reducing power consumption.
Which packages are the XC6401 series offered in?
The XC6401 series is available in SOT‑26W, USP‑6B and USP‑6C chip‑scale packages.
