Brief Introduction:
- This is a minimized Step-Up DC-DC converter module which provides easy-to-use and minimum number of external components power supply solution. Integrated with RT9266 chip which is a high efficiency, low voltage step-up DC/DC converter, this module can provide output voltage from 3.6V to 5.2V over a wide range of input voltage from 1.2V to 5.5V via the on-board adjustable resistor and deliver up to 500mA output current. This module can also be used for applications powered by one-cell, two-cell, or three-cell Alkaline, NiCd/NiMH, one-cell Li-Ion or Li-Polymer batteries in addition to 3.6V to 5.2V applications.
Features:
- Size of Step-up module: 24.70(L) × 24.70(W) × 26.30(H) ±0.2mm
- Size of converter board: 45.30(L) × 24.70(W) × 26.30(H) ±0.2mm
- Minimized and easy-to-use
