Features:
1. High Output Current: Capable of providing up to 3A with peak current provided up to 4A for high demand applications.
2. High Efficiency Conversion: Boasts a theoretical conversion rate reaching up to 95% making it an energy-efficient choice.
3. Over Current Protection and Thermal Shutdown Function: Ensures device safety as it automatically turns off once an overcurrent condition is detected or the device exceeds a certain temperature.
4. Versatile Voltage Input and Output: Supports a wide voltage input range from 5.5-28V and can provide dual positive and negative power outputs.
5. Low Quiescent Current: Draws only 17uA current when in the off-state, preserving energy.

Precautions for using:(1) The module is a step-down module, and the input voltage needs to be greater than the output IV to stabilize the output.(2) Module heating is mainly determined by the input and output voltage difference and the load current. Please select and use the power module reasonably. Generally, a certain margin should be reserved.3) The detailed description is mainly for positive and negative 5V output models, especially when using high power 10W (output 5V2A, output 15V/0.67A) or more, please add heat dissipation silicon grease heat sink to the chip Perform heat dissipation. With better heat dissipation conditions, it is best to control the long-term work within 30W (output 15V, 2A) to avoid damaging the chip.
Package Include:
1 x TPS5430 Dual Power Supply Switch Module

The following two are the measured ripple diagrams of the TPS5430 module of our store. Due to the influence of the tolerances of the components, there may be slight differences.What needs to know is that the greater the power supply, the greater the ripple; the greater the load, the greater the ripple.
