TPS5430 TPS5450 3A 5A Step-down Switching Power Supply Module DC DC Low Ripple

TPS5430 TPS5450 3A 5A Step-down Switching Power Supply Module

DC-DC Buck Low Ripple 3.3V 5V 9V 12V 15V 24V Voltage Output




 

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.

Notice:

 

1> The module is a step-down power supply module, and the input voltage needs to be greater 2V or more than the output voltage to stabilize the output;

 

2> The heating of the module is mainly determined by the input and output voltage difference and the load current. Please select and use the power module reasonably, and generally need to reserve a certain margin;

 

3> The above parameter description is mainly for 5V output. When using high power above 10W (input 5V2A, output 15V/0.67A), the module needs to strengthen heat dissipation, please install heat sink yourself. Even with good heat dissipation conditions, it is best to control it within 30W (output 15V 2A) for a long-term work to avoid damage to the chip.
