<p>The HM25030-3SR is a programmable dual switching regulator module, designed to provide a regulated +5V and +12V output. It is a highly integrated power management module with a simple set of commands to enable it to deliver precision power conversion. The compact size and low power consumption makes it suitable for low power applications. It can operate with input voltages ranging from 4.2V to 18V, making it compatible with most single cell lithium-ion batteries.</p><p>The design of the HM25030-3SR is based on two distinct types of synchronous switching regulators, the buck and boost. The buck converter is able to step down the input voltage to provide a regulated output voltage in either a high-side or low-side configuration. The boost converter is used when an output voltage higher than the input voltage is needed.</p><p>The HM25030-3SR provides a stable output to applications requiring both 5V and 12V voltage rails, such as mobile phone and camera charging, as well as industrial power supplies. The performance of the module is optimized to power the various loads that require a wide range of current levels. It features a full protection system, including over-voltage, under-voltage, and short circuit protection. It also includes a shutdown pin to turn off the module or to change the output voltage.</p><p>The HM25030-3SR is designed to operate with a wide input voltage range, ensuring the flexibility of design. It does not require the addition of external components for protection against output overvoltage or short-circuit. The module can be used in various applications such as tablet PC, recharging battery packs, supplying power for the automotive industry, and for consumer electronics.</p><p>The working principle of the HM25030-3SR is quite straightforward. It uses a buck and boost switching architecture to regulate its output voltage. This switch control can be controlled on-the-fly using an integrated PWM system or delayed equilibrium mode. The PWM simply switches the output voltage up or down depending on the requirements of the load. If controlling with the delayed equilibrium mode, the output voltage will raise or lower depending on the output current and output voltage setting.</p><p>The HM25030-3SR features a full protection system to ensure its safety and reliability in challenging applications. It offers both over-voltage and under-voltage protection for both outputs, as well as a short-circuit protection. It is also equipped with a wide temperature range of -25℃ to +85℃ which helps to ensure the maximum efficiency of the module.</p><p>In conclusion, the HM25030-3SR is a highly integrated, low power, programmable dual switching regulator module, designed to provide a stable 5V and 12V output. Its simple set of commands and wide input voltage range make it an ideal choice for many applications. With its comprehensive protection system and temperature range, it is a reliable and durable solution for providing a stable output voltage.</p>
