ADP2371ACPZ-R7 has become one of the most reliable and dependable voltage regulators in the market due to its features and versatile application field. This DC/DC switching regulator is designed to operate in either buck or boost converter topologies and is suitable for a wide range of applications including portable equipment, consumer electronics, industrial equipment, and several other applications. Moreover, it also serves as a cost-effective solution for applications that utilize multiple voltage rails.FeaturesADP2371ACPZ-R7 has a wide input voltage range of 0.8V–5.5V and an adjustable output voltage of 0.8V–5V. It is equipped with a low-side MOSFET and a synchronous P-Channel MOSFET, allowing it to handle up to 1.2A output current. The maximum switching frequency of the regulator is 800kHz, while it also supports adjustable soft-start and voltage tracking. Moreover, ADP2371ACPZ-R7 features a power-save mode which reduces the input power consumption and improves the efficiency of the regulator during light load conditions.Working principleADP2371ACPZ-R7 operates in either buck or boost converter topology. In buck mode, the regulator regulates the output voltage by controlling the duty cycle of the power switch (which is a low side MOSFET). This duty cycle is then determined by the voltage supervision window (VSOF), which is set via a single resistor connected to the VS block.During normal operation, the operating voltage is compared with the voltage supervision window. If the output voltage is higher than the VSOF, the device will enter the skip mode, reducing the power consumption and the output current. When the output voltage is lower than the VSOF, the power switch will turn on, switching the load electrode on the MOSFET. This will then drive current through the load and thus regulating the output voltage.In boost mode, the ADP2371ACPZ-R7 operates in a similar fashion to the buck mode but the main difference lies in the polarity of the power switch. Instead of turning the power switch on to drive current through the load, it turns the power switch off to create an inductive flyback voltage, which is then rectified and buffered to create the regulated output voltage.ConclusionADP2371ACPZ-R7 is a highly versatile and cost-effective DC/DC switching regulator which is capable of operating in either buck or boost converter topologies. It has a wide input voltage range and adjustable output voltage, allowing it to support multiple voltage rails. Moreover, it is also equipped with a power-save mode, adjustable soft-start and voltage tracking, making it an ideal choice for a wide range of applications.
