• Switching Frequency: 1MHz (typical)
• Efficiency: Up to 95%
• Operating Temperature Range: -40°C to +85°C
• Package: 8-pin TDFN (3mm x 3mm)

Descriptions:

• The MAX1561ETA+T is a synchronous step-up DC-DC converter optimized for low-input-voltage applications.
• It integrates power switches to minimize external components, making it suitable for space-constrained designs.
• Features a True Shutdown mode that disconnects the load from the input for zero power consumption.

Features:

• Low Start-Up Voltage: Operates down to 0.7V.
• Synchronous Rectification: Improves efficiency and reduces external diode requirements.
• Adjustable Output Voltage: Set via an external resistor divider.
• True Shutdown Mode: Disconnects the load from the input when disabled.
• Internal Soft-Start: Prevents inrush current at startup.
• Overcurrent and Thermal Protection: Enhances reliability.
