ADP2108AUJZ-2.5-R7 is a DC DC switching regulator belonging to the PMIC – Voltage Regulators family of semiconductor components. It is specially designed for boost or buck-boost applications. The device is compact, offers high integration and provides low noise operation in an extremely small package size.

The ADP2108AUJZ-2.5-R7 offers a stable and efficient way to regulate the input voltage to the output voltage required for many modern applications, such as mobile phones, notebooks and other portable electronics. The device works with a wide range of input voltages from 1.5V to 24V, and has an output voltage range from 3.2V to 24V. It supports up to 4A of continuous output current and can output peak current up to 5A.

The ADP2108AUJZ-2.5-R7 works in two operating modes, that is the Fixed Frequency Mode (FFM) and Variable Frequency Mode (VFM). In the Fixed Frequency Mode, the device operates with a fixed switching frequency of 2MHz, while in the Variable Frequency Mode, it can vary the frequency up to 4MHz, depending on the load requirements. This allows the device to be used in a variety of applications.

The device uses a high-side N-MOSFET and low-side P-MOSFET to regulate the output voltage. The high and low-side devices are connected in a buck-boost topology, and the output voltage is regulated using pulsewidth modulation (PWM). The device has high immunity to input and output voltage transients and is protected from over-voltage and over-current conditions.

The ADP2108AUJZ-2.5-R7 is programmable for a wide range of applications. It has a wide input voltage and output voltage range, a programmable switching frequency, programmable hysteresis voltages for the high and low sides, and can be configured to work in either continuous or discontinuous current mode (DCM and CCM).

In addition, the ADP2108AUJZ-2.5-R7 has integrated built-in safety features. It has an over-voltage protection (OVP) to protect against out-of-regulation output voltages, and an over-current protection (OCP) to protect against excessive load currents. The device also has an under-voltage lockout (UVLO) to prevent output voltage from dropping too low and a thermal shutdown circuit to protect against device over-heating.

The ADP2108AUJZ-2.5-R7 is a high-performance device providing a flexible, cost-effective and low-noise solution for many portable applications.
