The MAX757CPA+ is a Maxim Integrated step-up DC-DC switching regulator that can convert input voltages as low as 0.7V to output voltages up to 5.5V. This high-efficiency switching regulator is designed to power low-voltage microcontrollers and other low-voltage components in portable electronic devices. Its wide input voltage range, fixed 5V output voltage, and small form factor make it an ideal choice for powering low-voltage components from single-cell batteries or other low-voltage power sources.
Features and Specifications of MAX757CPA+, Maxim Integrated:
Design and Functionality:
The MAX757CPA+ uses a step-up switching regulator topology to increase the input voltage to the desired output voltage level. The regulator uses an internal MOSFET switch and synchronous rectifier to achieve high efficiency over a wide range of load conditions. The device also features soft-start and current limiting functions to prevent excessive inrush current during startup and overcurrent conditions.
Applications Information:
The MAX757CPA+ is an ideal solution for powering low-voltage microcontrollers and other low-voltage components in portable electronic devices such as:
It is also suitable for use in battery-powered devices that require a stable 5V supply voltage, such as handheld meters and sensors.
