MAX764ESA Typical application Circuitry

MAX764ESA

The MAX764ESA is a step-up DC-DC converter designed by Maxim Integrated. It is capable of providing higher output voltages from lower input voltages, making it particularly useful in battery-powered devices where the input voltage is lower than the voltage required by the system.

Application Scenarios

The MAX764ESA is commonly used in portable devices, battery-operated equipment, and applications requiring a step-up voltage conversion. It finds its applications in handheld instruments, medical devices, portable media players, and any system where a higher voltage is needed from a lower voltage source.

Parameter Features

- High Efficiency: The MAX764ESA offers high conversion efficiency, which is essential for maximizing battery life in portable applications.

- Adjustable Output Voltage: This feature allows for flexibility in response to varying application needs.

- Low Quiescent Current: By reducing power waste while in standby, its low quiescent current further improves its compatibility for battery-powered applications.

- Internal Oscillator: Equipped with an internal oscillator, this device requires fewer external components to function.

Application Scenario: Portable Medical Device

In a portable medical device that requires a specific operating voltage higher than what the battery can provide, the MAX764ESA can be used to step up the battery voltage to the required level.

- Input Voltage Connection: Attach the battery's input voltage (VIN) to the MAX764ESA's VIN pin. This is the lower voltage that will be stepped up.

- Ground Connection: Connect the ground (GND) of the battery and the system to the GND pin of the MAX764ESA to establish a common reference point for the circuit.

- Output Voltage Setting: To set the desired output voltage, connect a resistor divider between the feedback (FB) pin and the output voltage (VOUT) pin. The values of these resistors determine the voltage level stepped up to, according to the formula specified in the MAX764ESA datasheet.

- Capacitor Connections: To filter noise and offer stability, place a bypass capacitor next to the VIN pin and a capacitor at the output. The values and types of these capacitors are critical for optimal performance and should be chosen based on the recommendations in the datasheet.

- Inductor Selection: An external inductor is required between the LX pin and the output to store and transfer energy. The inductor's value affects efficiency, output ripple, and overall performance.

Design Considerations

- Output Voltage Requirements: Ensure the desired output voltage is within the capabilities of the MAX764ESA and properly set through the resistor divider.

- Load Current: Verify that the load current requirements of the medical device do not exceed the maximum output current capability of the MAX764ESA.

- Thermal Management: Consider the thermal aspects of the circuit, especially under maximum load conditions, to prevent overheating and ensure reliable operation.

- Component Quality: Use high-quality capacitors and inductors that meet the specifications for ESR (Equivalent Series Resistance) and current rating to ensure circuit stability and efficiency.

By adhering to these design principles, the MAX764ESA can be effectively integrated into portable medical devices, providing the necessary step-up voltage conversion to power the system reliably and efficiently.
