Introducing the MAX761CPA Step-Up DC-DC Converter from Maxim Integrated

Maxim Integrated's MAX761CPA is a versatile and efficient step-up DC-DC converter designed for a variety of applications. This high-frequency, voltage-mode, pulse-width-modulated (PWM) switch-mode converter is capable of delivering a stable and adjustable output voltage from a lower voltage input, making it an ideal choice for battery-powered devices, portable electronics, and any system requiring a voltage boost.

Key Features of the MAX761CPA

• Adjustable Output Voltage: The MAX761CPA offers an adjustable output voltage range, which can be set from 2.5V to 16.5V through an external resistor divider, allowing for flexible design options to meet various application requirements.
• High Efficiency: With efficiencies up to 94%, this converter helps to maximize battery life and reduce power loss, making it an energy-efficient solution for your power supply needs.
• Low Quiescent Current: The device features a low quiescent current of 110µA (typical) during operation, and only 12µA in shutdown mode, further extending battery life in portable applications.
• High Switching Frequency: Operating at a switching frequency of 300kHz, the MAX761CPA allows for the use of small, low-cost inductors and capacitors, which reduces the overall footprint and cost of the power supply design.
• Integrated MOSFET: The inclusion of an on-board N-channel MOSFET switch eliminates the need for an external power switch, simplifying the design and reducing component count.
