DC DC Switching Regulators are used for voltage regulation, which utilizes the well-designed control circuit to switch the energy between energy storage components of different electrical properties. This technology has a wide range of applications from switched mode power supply to battery management to LED lighting. The LMR23630DRRR is a step down DC to DC switching regulator module with integrated power MOSFET, providing high-efficiency, low-EMI, no-load quiescent current, adjustable output voltage and automatic power up sequencing control. It is designed to provides robust and reliable power generator for wireless and IoT applications.

The LMR23630DRRR operates in a fixed frequency PFM mode to offer excellent load and line regulation while operating at extremely low load current, due to its pulse width modulation (PWM) architecture. It provides an adjustable output voltage of 1.2V - 3.6V adjustable in 1mV step increments and can output up to 1A of current. With a 190mV dropout at 1A, the LMR23630DRRR can achieve over 95% peak efficiency. Furthermore, the LMR23630DRRR is designed with all the modern protection features, such as over-current protection, over-temperature protection, cycle-by-cycle current limit and short-circuit protection to ensure proper operation and to protect the module, load and power source.

The typical application field of LMR23630DRRR is the control of LED lighting. LED lighting requires complex current and thermal management because the power and performance can vary based on temperature and current. The LMR23630DRRR features features wide input voltage range, low-noise switching regulators to provide tight current, dimming and/or temperature control with minimum system complexity. The LMR23630DRRR also works well with powering small and medium sized batteries, such as Lithium-ion, and provides high efficiency, low output ripple and safe recharging for batteries with the adjustable output voltage of 1.2V - 3.6V.

The working principle of the LMR23630DRRR is based on the Pulse-Width Modulation (PWM) principle, in which a rectangular pulse signal is used to switch energy between energy storage components of different electrical properties. The PWM modulates the width of the switching signal that drives the MOSFET switch, thus controlling the output voltage. IIn the case of the LMR23630DRRR, the output voltage is regulated to within +/- 1.5V of set output voltage, and the output current is controlled with a linear loop to ensure a constant output current. The voltage error is then compared to a fixed reference voltage and a pulse-width modulating (PWM) signal is generated. This PWM signal then controls the switching MOSFET that generates the output voltage. The PWM modulation frequency of the LMR23630DRRR is 145 KHz with peak efficiency at 95%.

The LMR23630DRRR step down DC to DC switching regulator module is equipped with integrated power MOSFET, providing high-efficiency, low-EMI, no-load quiescent current and adjustable output voltage. It is applicable for LED lighting applications and for powering small and medium sized batteries with adjustable output voltage of 1.2V - 3.6V. The LMR23630DRRR operates in a fixed frequency PFM mode and utilizes the Pulse-Width Modulation (PWM) principle to offer excellent load and line regulation while operating at extremely low load current. With its high peak efficiency rate of 95%, the LMR23630DRRR provides robust and reliable power generator for wireless and IoT applications.
