The LMR33630ARN-XT is a DC-DC, non-synchronous Boost Converter, with all of its associated functions integrated into a single, easy-to-use package. It is specially designed for low-noise, high-efficiency applications in the power supply, consumer and medical markets. The LMR33630ARN-XT is a step-up switching regulator that operates from a 2.2V to 20V input range and supports output voltages up to 24V. Output current is adjustable up to 1.5A.

The DC-DC switching regulator market is highly competitive. To stand apart, the LMR33630ARN-XT has several key advantages. On the power management side, the IC combines a wide input voltage range, a low quiescent current, and a programmable switching frequency for high power efficiency. The high-precision input voltage and output current control allows for robust, stable performance. On the user experience side, the IC simplifies the design process with an easy-to-use package, comprehensive device documentation, and support from TI’s extensive technical community.

The LMR33630ARN-XT is a simple and efficient way to design high power and high accuracy DC-DC switch converters. Its integrated non-synchronous boost control topology is well suited for applications that require a wide input range. Its high level of integration prevents the need for additional components, reducing overall system cost. The 2-stage control loop maintains a constant output voltage while the on-chip Boost FET allows for very low current draw, high efficiency, and a fast load transient response.

The load of the converter is regulated by the current sense feedback. This helps to maintain the output current at the specified level and minimize the output voltage ripple. The current sense signal is then used by the PWM circuit to monitor the main current and finely control the output voltage. A compensation circuit is also included for extra control of the system to maintain stability.

The temperature protection circuit senses the temperature of the boosted FET and limits the maximum current delivered to the system during extreme temperature conditions, thus preventing damage to the system. The IC also incorporates many safety features such as overvoltage, overcurrent, and short-circuit protection.

All of these features combined make the LMR33630ARN-XT an ideal solution for design engineers who are looking for a compact and efficient DC-DC regulator solution. It is suitable for applications such as AC-DC adapter boards, display panels, consumer electronics, automotive applications, and medical systems.
