Maxim Integrated MAX1561ETA+T High-Efficiency, Low-EMI, Step-Up Converters

The MAX1561ETA+T from Maxim Integrated is a state-of-the-art high-efficiency, low-EMI step-up converter designed to provide a compact and efficient solution for small, portable electronics. This tiny, high-performance device is ideal for applications requiring a high voltage boost from a low-voltage power supply, such as powering white LEDs, OLED displays, and CCD sensors in portable devices.

With an input voltage range of 0.7V to 5.5V, the MAX1561ETA+T can start up with a cell voltage as low as 0.7V and run down to 0.5V, making it perfect for battery-operated devices. Once started, the device can operate down to input voltages of 0.5V. This feature ensures consistent performance over the entire battery life, which is particularly important for devices powered by single-cell batteries.

The MAX1561ETA+T employs an internal 2A, 0.3-ohm switch that can deliver output voltages up to 5.5V, allowing it to power a wide range of peripherals and components. Its high switching frequency of up to 2MHz minimizes the size of external components, further reducing the overall footprint and cost of the power supply design.

One of the key features of the MAX1561ETA+T is its low electromagnetic interference (EMI) characteristics, which are achieved through the use of a proprietary noise-reduction technique called spread-spectrum frequency modulation. This feature is critical in sensitive applications where EMI can cause malfunctions or degrade performance.

Additionally, the device includes a range of built-in protection features such as soft-start to minimize inrush current, thermal shutdown to protect against overheating, and current limit to prevent damage from overcurrent conditions.

The MAX1561ETA+T is available in a tiny 8-pin TDFN package, making it an excellent choice for space-constrained applications. Its high efficiency, low EMI, and compact size make it a versatile and reliable option for designers looking to optimize their power supply solutions.

Overall, the MAX1561ETA+T is a high-quality power management component that delivers performance, efficiency, and reliability for a wide array of portable electronic devices.
