TPS5430 Positive Negative Power Supply Regulated Power Supply Single to Dual Power Supply Output ±15V
Features:
- High Current Output: 3A (peak 4A). Wide Voltage Input Range: 5.5-36V. High conversion rate stands at 95%.
- Wide Voltage Output Range: Fixed 500KHz conversion rate.Over-current and over-temperature protections. With switch enable pin. Off state is with only 17uA quiescent current. Compared with other similar types of DC switching power supply conversion chips, the high conversion rate of the TPS5430 is more worthy of attention.
- Regular Layout: The layout and wiring are strictly in accordance with the filter circuit design, which features small ripples.
- Dual power outputs for easy application.
- Perfect for student competitions and personal project development.
Attention:
- When it is applied to ±15V power supply, supply voltage and the differential voltage of negative voltage should not exceed 36V.
- For other outputs, users need to adjust it by themselves. The output range of this module is preferably between ±3V to ±15V. When users configure the output voltage by themselves, the formula used is R2 = R1 * 1.221 / (VOUT-1.221) (Positive Voltage).
For example, when +5V output is needed, R1 is 10KΩ, and R2 should be 3.24KΩ. R4=R3*1.221 / (VOUT-1.221) (Negative Voltage).
When -5V output is needed, R3=10KΩ, and R4 should be 3.24KΩ. It is a step down module, so input signal should be greater than the output by over 1V.
When ±5V output is needed, input voltage should be over 6V. If ±12V output is needed, input voltage should be over 13V.
When ±15V output is needed, input voltage should be over 16V. Module Output Current: Positive Voltage@3A (Max.); Negative Voltage@2A (Max.).
Parameters:
- Item Name: TPS5430 Positive Negative Power Supply Module
- PCB Size: 50 x 50mm
- Compatible Supply Voltage: DC 5.5V-36V
Package Included:
- 1 x Power Supply Module
Note:
- It is recommended that the module is applied to power supply which is not over 30V and current within 2.5A.
- For uses with high power over 10W (output 5V/2A, output 15V/0.67A), additional thermal silicon, heat sinks, etc. to dissipate heat from the chip is needed. Please purchase separately.
- Under good heat dissipation conditions, it is recommended to control within 30W (Output 15V, 2A) to avoid damage to the chip.
