General Description
The MD3156 is a step-up converter that provides a boosted output voltage from a low voltage source.
Because of its proprietary design, it starts up at a very low input voltage down to 1.1V, and only consumes 15uA at standby, making it an ideal choice for single cell alkaline/NiMH battery operations.
Key Features
- Efficiency up to 95%@Vin=2.7V, VOUT=3.3V.
- Typical 15uA standby current.
- 1MHz Switching Frequency allows small inductor and output cap.
- Input boost-strapping allows using small or no input cap.
- Low Vin Start-up Voltage down to 1.1V Ideal for Single Alkaline Cell operations.
- Maximum Output Current up to 300mA.
- Low Noise PWM control.
- Internally Compensated Current Mode Control.
- Internal Synchronous Rectifier.
- Available in SOT23-3L、SOT23-5L and SOT8.
