### **Descriptions:**
The MAX628ESA+ is a high-efficiency, step-up DC-DC converter designed for low-voltage battery-powered applications. It integrates a power switch and can generate output voltages higher than the input supply. The device operates at a fixed 500kHz switching frequency, enabling the use of small external components.
### **Features:**
- **Wide Input Voltage Range (2.0V to 6.2V)** – Suitable for single-cell or dual-cell battery applications.
- **Adjustable Output Voltage (Up to 28V)** – Set using an external resistor divider.
- **High Efficiency (Up to 90%)** – Minimizes power loss in battery-operated systems.
- **Low Shutdown Current (1µA)** – Extends battery life when not in use.
- **Internal Power MOSFET** – Simplifies design and reduces external component count.
- **500kHz Switching Frequency** – Allows for compact inductor and capacitor selection.
- **Thermal Overload Protection** – Safeguards the device under fault conditions.
