LM5035ASQ/NOPB is a high-performance, monolithic synchronous buck controller that provides regulated output voltage adjustable from 0.625V to nearly 5V. The device is capable of output current levels up to 6A with low output ripple and excellent transient response. LM5035ASQ/NOPB also features integrated short-circuit protection, current limiter and thermal shutdown.

The LM5035ASQ/NOPB is designed to work as DC-DC switching controller in the power management integrated circuits (PMIC) module, specifically in the voltage regulator family. It can process power input from various sources of up to 12V and output at programmable voltage levels. That makes it suitable for use for batteries, USB ports and AC adapters.

In the switching regulator mode, the LM5035ASQ/NOPB can be used to switch its output voltage from 0.625V up to 5V. This mode of operation is made possible by using a linear regulator circuit, along with the integrated current limiting feature, which can be adjusted via external resistor. In this mode, the input source voltage is used to form the output voltage. This is a process known as pulse width modulation (PWM) which can be regulated either through a regulated source or by using an adjustable DC voltage source.

The LM5035ASQ/NOPB also works in an open-loop voltage mode. In this mode, the input voltage doesn\'t regulate the output voltage. Instead, the output voltage is solely determined by the external resistor. This mode is suitable for applications where precise voltage control is not necessary, such as when powering analog circuits or driving temperature sensors or other types of sensors.

The LM5035ASQ/NOPB also has a capability for voltage tracking, which allows for the output voltage to follow a regulated input voltage. This helps to reduce the number of components needed to adjust the output voltage, resulting in a more efficient power supply.

The device also integrates a low impedance power dissipation path for increased efficiency and reduced EMI. This feature will help to minimize the number of system components required, as there is no need to add separate power distribution components as would be done in a conventional design. Additionally, the LM5035ASQ/NOPB has an integrated analog proportional-integral (PI) loop, which helps to eliminate the need for external components to regulate the output voltage.

The LM5035ASQ/NOPB provides the flexibility and performance necessary for a wide range of DC-DC switching applications. By utilizing a PWM control architecture and integrating a wide range of integrated protection modes, it provides a cost-effective design solution for a wide range of applications, from 3.3V to 5V systems.
