LM2694MT/NOPB is a DC DC switching regulator from Texas Instruments’ family of PMIC (Power Management ICs). It is designed to deliver a constant voltage, which can range from 3.3 volts to 32 volts and supplies power to load currents up to 1.25A. It offers a wide input voltage range (minimum 7V, maximum 40V) and excellent line and load regulation.

This advanced, cost-effective power solution is suitable for a variety of applications demanding high efficiency and excellent transient response. It includes power MOSFETs and control logic integrated on a single chip, eliminating the need for external components such as inductors and discrete MOSFETs, thereby reducing cost and design complexity.

LM2694MT/NOPB features adjustable soft start and internal PWM frequency either fixed at 400 kHz or adjustable between 100 kHz and 600 kHz. It helps reduce overtemperature shutdown standby current and ripple current. Also, the device provides current limiting and overtemperature protection, as well as soft-start ramp control. The wide input voltage range and excellent transient response are ideal for automotive applications.

LM2694MT/NOPB\'s Efficiency is 96-99.5% and it is available in SOIC-8 or DFN-8 package. Its typical applications are Automotive, Low Power Industrial, Medical, Telecom and Home Appliances, etc.

The working principle of LM2694MT/NOPB is simple. It uses a power MOSFET and high side current limit to regulate the output voltage. The input voltage is converted to a switching signal which is then fed to a control logic circuit. The logic circuit then lowers the voltage at the source of the power MOSFET, resulting in a lower output voltage. This provides regulation of the desired output voltage and current limit.

When working with LM2694MT/NOPB, it is important to pay attention to physical layout as this may affect the performance and reliability of the output voltage. It is important to ensure that the input and output pins are properly decoupled and the power supply is protected from surges or spikes. To ensure the best performance, it is also important to use proper shielding and grounding techniques.
