Maxim Integrated MAX1624EAG Step-Up DC-DC Controller

The MAX1624EAG from Maxim Integrated is a high-efficiency, step-up DC-DC controller designed to provide a compact and flexible solution for power supply applications. This advanced component is ideal for converting low-voltage inputs into higher output voltages required by a variety of electronic devices, ranging from portable gadgets to industrial equipment.

Featuring a wide input voltage range of 1.8V to 11V, the MAX1624EAG can accommodate a variety of power sources, including single-cell batteries or multi-cell battery stacks. The device is capable of producing an adjustable output voltage up to 28V, making it highly versatile for different design requirements.

The MAX1624EAG utilizes a current-mode control architecture, providing excellent transient response and simplifying the loop compensation design. It also boasts a high switching frequency of up to 300kHz, which allows for the use of smaller, low-cost inductors and capacitors, thereby reducing the overall solution size and bill of materials.

One of the key features of the MAX1624EAG is its high efficiency, which is achieved through the use of low on-resistance (R<sub>DS(ON)) MOSFET drivers. This characteristic ensures minimal power loss during operation, thereby extending battery life for portable applications. Additionally, the device includes a power-saving shutdown mode that reduces the quiescent current to just 15µA, further conserving power when the device is not in use.

The MAX1624EAG also incorporates a range of protective features to ensure reliable operation under adverse conditions. These include cycle-by-cycle current limiting, thermal shutdown, and frequency foldback to prevent excessive power dissipation during overload conditions.

Available in a 24-pin SSOP package, the MAX1624EAG is designed for easy integration into a wide array of applications. Whether for powering OLED displays, creating a high-efficiency power supply, or designing a regulated power source for communication devices, the MAX1624EAG offers a robust and efficient solution for your step-up DC-DC conversion needs.
