SC900841JVK is a power management integrated circuit (PMIC) designed for specialized applications. It provides four channels of tightly regulated power output, allowing a maximum load current of 5A.

Despite its small size, SC900841JVK packs six power stages (DC/DC converters and LDO regulators) in a single chip. The chip is optimized for battery-powered applications, offering a maximum power efficiency of 98%. It has multiple protection features, including under voltage lockout (UVLO), current sensing, thermal protection, and over voltage protection (OVP).

The device is ideal for applications such as medical devices, connected home appliances, and portable devices, where high power density, absolute power system stability, and maximum efficiency are of utmost importance. It offers a low total system cost, fast time-to-market, and superior design flexibility.

Working Principle

The SC900841JVK is designed around a novel architecture which introduces an innovative concept — differential regulation — to the PMIC world. This enables the device to deliver an active-mode power conversion loop, with independent control of each output voltage, allowing the device to stay regulated, nominal and efficient over a wide range of load conditions.

In active mode, the device actively regulates the output voltage by monitoring the load current and voltage simultaneously, and controlling the output voltage by varying the on/off duty cycle of the respective power stage. This is in contrast to traditional PMICs, which rely on a purely passive loop, with a large margin for their respective output voltages.

The SC900841JVK also features a unique synchronous mode, which allows for the supply of any output voltage with an efficiency of up to 95%. This means that the device is able to simultaneously provide multiple output voltages, while remaining efficient and providing superior thermal and performance advantages over conventional solutions.

In addition, SC900841JVK has a number of protections, including over-temperature protections, under-voltage protection (UVLO), over-voltage protection (OVP), and current-sense protection. All of these measures ensure that the device\'s operation is safe and reliable.

Conclusion

SC900841JVK is a highly advanced power management integrated circuit designed for specialized applications, such as medical devices and connected home appliances. The device packs six power stages in a single chip, offering maximum power efficiency and an innovative active mode differential regulation system for superior performance and reliability. In addition, the device features various protections, such as UVLO, OVP and current sense protection, to ensure the device\'s safe and reliable operation.
