MAX772CSA is a high-efficiency, low-noise step-up DC-DC converter that provides a comprehensive power management solution. It is an integrated circuit component manufactured by Maxim Integrated Products. Here is an overview and key features of MAX772CSA:
- The MAX772CSA is capable of operating from a single Lithium-ion (Li+) cell or two to three cells of Nickel Metal Hydride (NiMH), resulting in an output voltage of up to 28V. This wide input voltage range makes it suitable for a variety of portable electronic devices.
- This IC is designed to maximize efficiency. It achieves up to 96% peak efficiency, ensuring the conversion of input power to output power with minimal energy loss. Additionally, the IC employs a pulse-frequency modulation (PFM) control technique to further enhance efficiency during light load conditions.
- The MAX772CSA incorporates a low-noise, 1.5A power MOSFET switch, which efficiently drives the power supply. The advanced gate-drive architecture reduces both switching losses and electromagnetic interference (EMI).
- It includes an integrated fault detection circuitry, which safeguards against output overvoltage, output undervoltage, and overcurrent conditions. These protection features improve the reliability and durability of the power supply system.
- This component offers flexible control options, allowing the user to select between PWM (pulse-width modulation) and PFM operation modes
