The MAX757CPA+, Maxim Integrated, is a small step-up DC/DC switching regulator designed to power low-power components. It is widely used in portable electronics and is lightweight, durable, and inexpensive, making it ideal for professionals.
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:
The MAX757CPA+ offers a wide input voltage range from 0.7V to 5.5V, making it suitable for use with a variety of power sources, including single-cell batteries.
It has a fixed output voltage of 5V and a maximum output current of 80mA.
The switching frequency is set at 250kHz, which allows for the use of small external components.
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:
Smartphones
Tablets, and
Portable media players.
It is also suitable for use in battery-powered devices that require a stable 5V supply voltage, such as handheld meters and sensors.
