Description
General part information
TPS54201 Series
The TPS54200 and TPS54201 devices are 1.5-A synchronous buck mono-color or IR drivers with 28-V maximum input voltage. Current-mode operation provides fast transient response and eases loop stabilization.
The TPS54200 and TPS54201 can be used to drive single-string or multi-string mono-color or Infrared (IR) LED arrays as in the case of night vision cameras.
By integrating the MOSFETs and employing the SOT-23-THIN package, the TPS54200 and TPS54201 devices provide high power density and only require a small footprint on the PCB.
