The MAX20003ATPB/V+T device is a small, step-up power-management integrated circuit (PMIC) with high efficiency, low quiescent current and wide output voltage range capabilities. It belongs to the category of DC-to-DC switching regulators and is often used for applications such as Digital Multimedia Cards (DMCs), memory cards, USB-to-UART converter circuits, LCD panels, power-detecting circuits, and optical sensors. This chip offers a regulated output voltage ranging from 2.7V to 6V with a maximum output current of 2A.

Though the MAX20003ATPB/V+T device is an off-the-shelf product, it has customizable parameters that can be set up for the specific application for which the device is being used. The device is powered by a Liebert LP06 or LT15 power supply and accepts the input voltage range from 2.7V to 6V. The device supports multiple programmable output voltage options and includes an adjustable soft-start feature. It offers an integrated 400mV reference voltage to support a fixed output voltage or with external resistors, an adjustable output voltage.

The MAX20003ATPB/V+T device features an advanced Burst Mode® operation, where it enters a low power consumption mode after a predetermined load current threshold. This allows the device to maintain the total system power consumption in the low power consumption mode. It is also equipped with cycle-by-cycle current limiting, thermal shutdown protection, as well as over-voltage and undervoltage protection features. This chip also offers a two-stage enable output enable voltage (ENV) reducing the total power consumption.

The device enables a novel scheme for the design of power conversion circuits. It uses a pulsed operation for input-boosting, output-boosting and output-clamping stages and resulting in high energy effective operation. In addition, the device includes a BiCMOS synchronous buck topology, which offers high-efficiency over a wide input voltage range. Furthermore, with its integrated gate driver, the MAX20003ATPB/V+T device minimizes external components requirements and reduces the board space.

In summary, the MAX20003ATPB/V+T PMIC is a high-efficiency, low quiescent current, step-up voltage regulator tailored for a wide range of applications. It is equipped with adjustable soft-start feature, advanced Burst Mode® operation, high-performance synchronous buck topology and integrated gate driver, making it a suitable choice for applications requiring high efficiency and low power consumption.
