PMIC - Voltage Regulators - Linear + Switching

ADP5033ACBZ-1-R7 is a product of Analog Devices renowned power management integrated circuits (PMIC) family. It has a fully integrated power-path management with high-frequency, high-efficiency switches and linear regulators. ADP5033ACBZ-1-R7 is a high-performance Step-up capacitor-less DC-DC power solution for USB power applications, drawing power from a single-cell Li-ion battery.The ADP5033ACBZ-1-R7 offers robust protection options to keep the system safe. It provides up to 2A of steady-state boost current, the ability to support a wide range of input voltages while adjusting the output voltage according to the maximum allowed charge rate, as well as current-limit protection. Plus, its low quiescent current of 150 nA in sleep mode helps keep the amount of power drained by the device as low as possible.In terms of application field, the ADP5033ACBZ-1-R7 is used as a portable platform for designing consumer electronic accessories about smartphones, tablets, other small electronic devices, and even power bank. As for features, it combines high efficiency in power conversion and an ultra-low operating current with very competitive cost. Low development costs are possible since ADP5033ACBZ-1-R7 integrates components that are commonly employed for cellphone powered devices.Now let’s get into the working principle of the ADP5033ACBZ-1-R7.It is based on switching and linear regulation. Switching regulation is used to achieve high conversion efficiency that allows the device to operate in steps and reach higher output accuracy. When the input voltage is low, the “step-up” circuitry produces a higher output voltage than the input one; when the input voltage is higher than the output, the linear regulator produces the required protection by limiting the current to reach the right voltage. The device keeps monitoring the current flows, so it can quickly adjust the voltage levels according to the output requirements.The ADP5033ACBCZ-1-R7 has a wide range of safety and protection features. It employs analog and digital power monitors that timely detect any system overload. Its integrated closed-loop control circuits detect the output voltage and current, then adjust the required settings to attain the expected working state with the minimum amount of power consumption. Also, it is capable of sensing accidental short or open-circuit conditions, and shut down the output for preventing damage to the system.To sum up, the ADP5033ACBCZ-1-R7 is a high-end PMIC linear and switching voltage regulator that is suitable for power management applications in consumer electronic accessories like smartphones, tablets and power banks. It offers robust protection options and high conversion efficiency with a low virtual current that help keep the system safe and save power.
