What is TPS562200?

The TPS562200 is a 2-A synchronous buck converter that integrates high-side and low-side MOSFETs, enabling high efficiency and low power loss. It is optimized for converting higher DC voltages (such as 12 V or 24 V rails) down to lower voltages like 5 V, 3.3 V, or core voltages for microcontrollers and processors.

Thanks to its 600 kHz switching frequency, the TPS562200 allows the use of small inductors and capacitors, resulting in compact power supply designs.
