TPS54283 and TPS54286 are dual output non-synchronous buck converters capable of supporting 2-A output applications that operate from a 4.5-V to 28-V input supply voltage, and require output voltages between 0.8 V and 90% of the input voltage.

With internally-determined operating frequency, soft start time, and control loop compensation, these converters provide many features with a minimum of external components. Channel 1 overcurrent protection is set at 3 A, while Channel 2 overcurrent protection level is selected by connecting a pin to ground, to BP, or left floating. The setting levels are used to allow for scaling of external components for applications not needing the full load capability of both outputs.

The outputs may be enabled independently, or may be configured to allow either ratiometric or sequential startup sequencing. Additionally, the two outputs may also be powered from different sources.

TPS54383EVM — TPS54383 12 V-Eingang, Dual-5 V- und 3,3 V-Ausgang, 2 A, Evaluierungsmodul

The TPS54383EVM evaluation module (EVM) is a dual non-synchronous buck converter providing fixed 5.0 V and 3.3 V output at up to 2 A each from a 12 V input bus.

The EVM is designed to start up from a single supply, so no additional bias voltage is required for start-up. The module uses the TPS54383 (...)
