MAX5035DASA Application Field and Working Principle

MAX5035DASA is a low-voltage, high-output current DC-DC switching regulator that operates from a wide voltage range of 4.75V to 22V. The device has an adjustable output voltage of 0.8V to 17V and is capable of sourcing up to 2A of output current.MAX5035DASA is typically used in applications requiring high output current and/or low-noise operation. It features a wide input voltage range, low dropout voltage, high efficiency, and adjustable output voltage and current limit. It is primarily used in automotive, medical, industrial, and communications applications.

How it Works

The MAX5035DASA DC-DC switching regulator features a pulse width modulation (PWM) technique to generate an output voltage or current. The device has an internal oscillator and soft-start to provide a precise frequency and output voltage accuracy.The MAX5035DASA operates in a voltage mode and incorporates a high-side P-channel pass MOSFET switch. The device provides a precise current-limit threshold to protect against overload and short-circuit conditions. The input and output voltage levels are sensed using differential voltage amplifiers. When the output voltage reaches the desired level, the internal oscillator enables the P-channel MOSFET switch and pulls the output node to ground.When the current limit is reached, the device stops switching and a latch-off circuit trips without causing an excessive positive voltage overshoot. There is also a thermal shutdown circuit to protect against excessive temperatures.

Benefits of Using the MAX5035DASA

The MAX5035DASA is designed to meet automotive applications and is AEC-Q100 compliant for quality assurance and long-term reliability. Its wide input voltage range, small package size and high efficiency make it ideal for demanding applications in harsh environments. The device offers low quiescent current, fast transient response, and over-voltage and over-temperature protection. The MAX5035DASA is also user-friendly, allowing designers to set the output voltage and current limit by simply connecting two external resistors. Its low output ripple and high noise immunity make it suitable for medical applications.Overall, the MAX5035DASA is an ideal low-voltage, high-output current DC-DC switching regulator for various test and measurement, automotive, industrial, medical, and communications applications. Its easy-to-use features, low dropout voltage and high efficiency make it an attractive choice for designers looking for a convenient and cost-effective solution.
