Description:

This is a buck power supply module with High current output: 3A(TPS5430) or 5A(TPS5450) and wide input voltage range: 5.5V-36V . By short-circuiting the pads at the corresponding output voltage positions, multiple output voltages of 3.3V/5V/9V/12V/15V/24V can be obtained (simultaneous output of multiple voltages is not supported). The theoretical conversion efficiency can reach up to 95%. Wide voltage output range, fixed 500KHz conversion rate, with overcurrent protection and thermal shutdown function, with switch enable pin, only 18uA in off state. The module layout is regular, strictly in accordance with the power circuit design specifications, high-end materials are used, and the ripple is small. A variety of output voltages, suitable for student graduation competition design and personal project development, very practical.
