Brief Introduction:
- This is a compact, high-efficiency, fixed frequency, synchronous step-up DC-DC converter. It provides an easy-to-use power supply solution for applications powered by one-cell, two-cell, or three-cell alkaline, NiCd, NiMH, one-cell Li-Ion or Li-Polymer batteries. Fed with DC supply from 0.7V to 5.5V, this module can output a wide range voltage from 2.0V to 5.5V.
Features:
- Size: 46.07(L) × 25.76(W) × 17.60(H) ±0.2mm
- DC-DC step-up converte
- Up to 96% efficiency
- 800 mA typical peak input current limit:
- IOUT > 100 mA @ 1.2V VIN, 3.3V VOUT
- IOUT > 350 mA @ 2.4V VIN, 3.3V VOUT
- IOUT > 350 mA @ 3.3V VIN, 5.0V VOUT
- Low start-up voltage: 0.65V, typical 3.3V VOUT@ 1 mA
- Low operating input voltage: 0.35V, typical 3.3VOUT @ 1 mA
- Adjustable output voltage range: 2.0V to 5.5V
- Low device quiescent current: 19 μA, typical
- Default DC5V output
- Cost effective and easy to use
- Inrush Current Limiting and Internal Soft-Start
- Low noise, anti-ringing control
- Thermal protection
- Mounting holes facilitate installation and fixing
