The 15V TPS5430 Switching Power Supply Module is a compact, high-efficiency solution for powering electronics projects, industrial devices, and DIY circuits.
Designed with a 50 × 50 × 12mm layout, it fits easily into various setups while delivering stable output with minimal ripple. The module features overcurrent and thermal shutdown protection, ensuring safe operation.
With a wide input range of 5.5–28V and selectable output voltages (5V, 12V, 15V), it supports high-demand devices and offers dual positive/negative output. Perfect for operational amplifiers, LED lighting, communication equipment, and educational projects requiring reliable and efficient DC power.
Features:
- High current output: 3A continuous, 4A peak.
- Wide input voltage range: 5.5–28V.
- High efficiency: up to 95% theoretical conversion.
- Dual output: positive and negative voltage support.
- Fixed 500 kHz switching frequency for stable operation.
- Built-in overcurrent and thermal shutdown protection.
- Low standby current: 17 µA in off state.
- Compact and organized layout with minimal ripple.
Notes:
- This is a step-down module; input voltage must exceed output by >1V for stable operation.
- Heating depends on input/output voltage difference and load; keep a margin for safe use.
- For high-power use (>10W), add heat-dissipating fins; long-term operation above 30W (15V/2A) may damage the chip.
