ZHCSL70D March 2020 – October 2020 TPS63900
PRODUCTION DATA
The TPS63900 device is a four-switch synchronous buck-boost converter with a maximum output current of 400 mA. It has a single-mode operation that allows the device to regulate the output voltage to a level above, below, or equal to the input voltage without displaying the mode-switching transients and unpredictable inductor current ripple from which many other buck-boost devices suffer.
The switching frequency of the TPS63900 device varies with the operating conditions: it is lowest when IO is low and increases smoothly as IO increases.
