TPSM84A21MOJT

The TPSM84A21 is an easy-to-use integrated power supply solution that perfectly combines the TPS54A20 10A DC/DC synchronous buck converter with power MOSFETs, isolated inductors, input and output capacitors, and passive components in a thin package. This complete power supply solution only requires one resistor to set the voltage, and there is no need to consider loop compensation and magnetic component selection during the design process. For standard applications, with this fully integrated power supply solution, it can operate normally without using additional input or output capacitors, and the output voltage can be set with just one external resistor. In addition, the TPSM84A21 supports high-frequency operation, while having ultra-fast transient response and precise voltage regulation capabilities, easily meeting strict voltage regulation specifications. This device features a compact size of 9mm×15mm, making it easy to solder on the printed circuit board to create a compact and thin point-of-load design.
