Texas Instruments TPS60402 | Demoboard TIDA- 010018
Isolated power and data interface for low-power applications reference design
Details
| Topologie | Abwärtswandler |
| Eingangsspannung | 4.4-5.25 V |
| Ausgang 1 | 3.3 V / 0.01 A |
| IC-Revision | 2 |
Beschreibung
This reference design provides power and data isolation for low and ultra-low power applications. Generating isolated and non-isolated power rails with a high efficiency and containing a power efficient isolated data interface for three forward- plus one reverse-direction channels. Targeted applications are isolated loop powered 4- to 20-mA transmitters. This design can be adapted to other applications requiring highly-efficient power conversion and isolated data transmission while being powered from sources with a limited current capability.
Eigenschaften
- Power input 5 VDC, source needs to be current limited to < 30 mA
- Ultra-low power, isolated data interface
- 5, 16, 130 μA per channel at 10, 100, 1000 kbps
- 3 forward-channels, 1 reverse-channel
- Isolated 10-mA DC/DC Converter Efficiency up to 86.5%
- 3.3-V, 10-mA buck converter on non-isolated side Efficiency up to 93%, VOUT ripple < 15 mVpp
- 3.3-V, 10-mA buck converter on isolated side Efficiency up to 92%, VOUT ripple < 20 mVpp
- 3.0-V, 10-mA LDOs IQ = 16 μA @ Iout = 1 mAPSRR > 36 dB at ≤ 200 kHz
Typische Anwendungen
- Temperature transmitter / Flow transmitter / Pressure transmitter
