Switch mode power supplies (SMPS), otherwise known as DC to DC converters, are the modern power designers go-to choice for efficiently converting one voltage level to another. They are capable of greater efficiency ratings compared to linear power supplies, because instead of relying solely on the resistive and inductive elements working in an energy-consuming load, SMPS boost and buck the voltage levels to achieve voltage conversion with minimal energy losses.

The NCV891330PD38R2G is a switched-mode power supply designed specifically to provide power to devices that must meet global standards for standby or sleep mode operation. It is understood that this device operates in a dual-mode state, meaning that it has two distinct operating modes that it can operate in — either 1) a standby mode where the output voltage is restricted to <0.5V and the output current is limited to a maximum of 5 mA or 2) an active mode where the output voltage can be adjusted within a 1.8V-3.6V range, and the output current is limited to a maximum of 50mA.

The NCV891330PD38R2G convert power by use of two main operating principles, bucking and boosting. Bucking involves reducing the incoming voltage to a lower output voltage, and boosting involves increasing the input voltage and regulating it at a set desired level. In both instances, the device draws power from the input power source, reduces it or boosts it, and then stores it in an energy storage element such as a transformer, capacitor, or inductor from which it can be taken later as needed.

The NCV891330PD38R2G has become a go-to choice for many applications due to its fast switching frequency (1.5MHz typical), low quiescent current (20uA typical, 10pA max during shutdown mode), low power operation (1uW typical, 65mW max), and low dropout (only 10 mV). With such low power operation, minimal power is wasted and the device can generate higher efficiency ratings compared to linear power supplies.

The NCV891330PD38R2G is well suited to many applications including near-field communication (NFC) systems, wearable devices, internet of things (IoT) applications, power sensitive graphic display systems, and battery-powered systems. The device can also be used to replace linear regulators within battery-powered systems to help cut down on power losses. Additionally, its fast switching frequency makes it suitable for powering slow transition circuits, such as A/D converters.

In conclusion, the NCV891330PD38R2G is an excellent DCDC switching regulator that provides flexibility, convenience, and very low power consumption. Its robust feature set, such as its dual-mode operation, fast switching frequency, low quiescent current, low power operation, and low dropout make it an ideal choice for many power-sensitive applications.
