DC-DC converters are important components used in the power management stacks of applications such as Internet of Things (IoT) and Autonomous applications that are becoming increasingly more complex day by day. DC-DC converters provide power to the system and, depending on the application, they can also provide noise filtering or voltage regulation. The LW015A8 DC-DC converter is a high-efficiency, low-power step-up DC-DC switch mode power converter. It is designed to extend the battery life of applications that include energy-harvesting, ultra-low power, remote sensors, wearable electronics, as well as impulse power supply applications that use small voltage sources.

LW015A8’s power management system is capable of supplying up to 1.5A of continuous output current from a single cell input. Operating from a wide input range of 0.9V to 3.6V, it offers an output voltage adjustable to a maximum of 18V. The converter also features an excellent 130db peak power supply rejection ratio, 1% line voltage regulation, and an efficiency of up to 98%.

The working principle of LW015A8 is based on switch-mode conversion. A switching element such as a Power MOSFET is used to store energy in an inductor during the period when the switch is on and discharge it into the output capacitor when the switch is off. By modulating the transitions of the switch, the converter dynamically alters the frequency and amplitude of the input current to keep the output voltage regulated. This materializes into an efficacious solution to transfer energy from the source such as a battery to the load in ultra-low power applications.

The LW015A8 converter is an ideal choice for applications that require relatively low power, but require a wide adjustable output voltage. Because of its high efficiency, superior power supply rejection ratio, small form factor, and its robustness, the LW015A8 is an ideal choice for powering a range of electronic devices such as smart home devices, industrial sensing devices, and any other energy-harvesting systems.

In conclusion, the LW015A8 DC-DC converter is a highly advanced step-up DC-DC switch mode power converter that is capable of delivering up to 1.5A of output current from a single cell input. It offers a wide adjustable output voltage, excellent power supply rejection ratio, 1% line voltage regulation, and high efficiency of up to 98%. The LW015A8 is an ideal choice for powering a range of electronic devices such as smartphones, smart home devices, industrial sensing devices, and any other energy-harvesting systems.
