7Semi DC-DC Buck Boost Converter 1.6V-5.5V Input to 3.3V 1.5A Output - TPS631000
The 7Semi DC‑DC Buck‑Boost Converter (TPS631000) delivers a regulated 3.3 V output across a wide input range from 1.6 V to 5.5 V. It’s tailored for systems where the supply voltage can fluctuate above and below the target output voltage, such as battery-powered devices. The converter automatically switches between buck, boost, and buck-boost operation, providing seamless and efficient regulation.
Technical Specification:
- Input Voltage Range: 1.6 V to 5.5 V
- Output Voltage: 3.3 V fixed
- Output Current: Up to 1.5 A
- Switching Frequency: ~2 MHz
- Quiescent Current: ~8 µA
- Peak Switch Current: ~3 A
- Efficiency: Up to 96%
- Protections: Short-circuit, overcurrent, overtemperature
Features:
- Automatic buck‑boost mode
- Low quiescent current (ultra‑low power consumption)
- Compact design with minimal external components
- Internal compensation and soft start
- High switching frequency reduces external inductor size
- Thermal and overcurrent protection
- Supports direct battery and USB-powered applications
Applications:
- Battery-powered and wearable electronics
- IoT sensor nodes and microcontroller boards
- Portable medical equipment
- Low-power embedded systems
- Energy harvesting and capacitor-powered circuits
