The LM46002PWPT voltage regulator is an efficient, low-cost DC-to-DC switching regulator that is well suited for use in embedded applications. It is part of the family of voltage regulators from Texas Instruments that allow users to easily add high efficiency, small-footprint voltage regulation to their designs. The LM46002PWPT is optimized for a wide range of input voltages, from 4.5V to 36V, and output voltages up to 25V. It is a quiescent current switched capacitor type DC-DC converter that operates at high frequency, providing a low noise and compact solution.

This voltage regulator includes built-in soft-start and provides output voltage with a precise +/-1% tolerance. It also features a variety of features such as power good indication, current limit protection, and short circuit protection. The output voltage can be adjusted with an external resistor, while the switching frequency can be adjusted with an on-chip resistor. These features make it ideal for use in systems where tight output voltage regulation is required.

The LM46002PWPT voltage regulator is designed to operate up to 75KHz with efficiencies up to 96%. This makes it well suited for designs that need to maximize power efficiency while minimizing board area. Additionally, the low noise and low EMI emissions of the device make it an ideal choice for battery-powered applications in confined spaces.

This voltage regulator also has excellent thermal performance. It is capable of running at full load with no additional cooling, and it has a low maximum junction temperature rating of 120°C, making it suitable for use in high-temperature applications. Furthermore, it is also available in various package options, allowing designers flexibility and scalability. The LM46002PWPT is also highly configurable, allowing users to tailor the design of the chip to their specific application.

The LM46002PWPT voltage regulator utilizes a synchronous rectified forward converter. This circuit includes an active switch MOSFET that is connected to the input voltage and a diode that is connected to the output voltage. When switched on, the MOSFET pulls current from the input voltage and the diode is allowed to charge the output capacitor, resulting in a regulated output voltage. The operating frequency of the regulator is controlled by an oscillator, and the duty cycle is adjusted to regulate the output voltage.

The LM46002PWPT voltage regulator is a rugged, reliable, and efficient solution for embedded applications. Its features and performance make it an ideal choice for designs that require tight output voltage regulation, high efficiency, minimal board area, and high standards of quality and reliability. The device is even designed to meet specific safety standards, making it suitable for use in a wide variety of applications.
