PMIC - Voltage regulators - DC/DC switching regulators is a type of regulated power source due to its capability to maintain consistent output voltage in the presence of fluctuation in the input voltage. The ADP2504ACPZ-3.5-R7 device from Analog Devices is a highly efficient, monolithic, fully integrated, single switch DC/DC regulator for lowvoltage applications. It integrates the power switch, control logic, current sensing, voltage regulation and protection circuitry in a single 4-pin TSOT package.
The ADP2505ACPZ-3.5-R7 device is designed to produce an adjustable regulated output voltage between 0.5 V and 3.3 V (depending on version) with a maximum current rating of 500 mA.
The device operates in switching mode so that the power conversion output is much more efficient, reducing power losses and improving efficiency. The device also offers a wide input voltage range that makes it suitable for applications such as 3 V and 5 V input supplies, which is useful when a single supply voltage is required. The versatile device is designed to regulate the output voltage at relatively high output current levels.
As with other PMIC - Voltage regulators - DC/DC switching regulators, the ADP2505ACPZ-3.5-R7 device offers several advantages over other solutions. It has low quiescent current, low EMI, high efficiency and good load regulation. The device requires minimal external components, reducing system complexity and cost. It also operates over a wide input voltage range and temperature range.
The main application for this device is for low voltage power supplies such as mobile handsets, digital still cameras and PDAs. It is also useful in automotive and industrial applications. The device’s wide input voltage range makes it suitable for portable applications that require a single supply voltage. It is also suitable for applications where power efficiency is important, such as battery-powered systems.
The ADP2505ACPZ-3.5-R7 device is intended to operate as a non-synchronous step-down regulator. It has an internal PWM controller and an internal power switch. The device is designed with a analog sensed feedback loop for constant voltage regulation and current mode for switching control. The output voltage is regulated as long as the input voltage is within the specified range. Additionally, the device integrates an adjustable soft-start circuit to limit the in-rush current during startup.
It is important to note that the device is not intended to be used as a synch step-down regulator and is not designed to produce bipolar outputs. It is also not designed to operate from low impedance sources, such as batteries. Such sources can cause the device to draw large amounts of current during operation, risking damage and inefficiency. Therefore, a separate external regulator may need to be employed for such applications.
In summary, the ADP2505ACPZ-3.5-R7 is a highly efficient, monolithic, fully integrated, single switch DC/DC regulator for low voltage applications. It is suitable for applications such as mobile handsets, digital still cameras and PDAs. The device offers several advantages such as low quiescent current, low EMI, high efficiency and good load regulation. The key application of the device is for low voltage power supplies, but it can also be used in automotive and industrial applications due to its wide input voltage range.
