It is also suitable for single-cell Li-ion battery charging, automotive electronics, industrial motor control and other applications where an adjustable, regulated output voltage is required.

The ADP2165ACPZ-1.2-R7 is an ideal choice for a variety of power supply and DC-DC converter applications. Its wide input voltage range, accurate error amplifier and over-temperature protection ensure reliable operation and excellent thermal performance. Its adjustable frequency, adjustable soft-start/soft-stop control, and output voltage sequencing make it a flexible solution for many applications.

The working principles of the ADP2165ACPZ-1.2-R7 involve synchronous buck conversion. When the output voltage demand is higher than the available input voltage, the regulator turns on the external power MOSFET switch and the synchronous rectifier. The switch is turned on by a signal generated by the integrated feedback loop error amplifier. The power MOSFET switch operates in continuous conduction mode as well as in off-time mode. When the switch is in continuous conduction mode, energy is stored in a capacitor and the buck converter operates at maximum efficiency. When the switch is in off-time mode, the stored energy helps to provide power to the load.

The ADP2165ACPZ-1.2-R7 also contains an adjustable current limit protection circuit. This is activated when the output load current exceeds the programmed current limit and shuts off the MOSFET to protect the system from damage. The device also contains an automatic self-reset circuit that can recover from an overtemperature condition, as long as the temperature returns below a preset value.

In summary, the ADP2165ACPZ-1.2-R7 is an ideal choice for a variety of power supply and DC-DC converter applications. It is an integrated switching regulator IC that is designed to provide a regulated output of 1.2V at up to 4A load current. It features wide input voltage range, adjustable frequency and adjustable soft-start/soft-stop control, as well as output voltage sequencing. The integrated MOSFET, accurate error amplifier and hem protection circuitry provide excellent thermal performance and reliable operation. Its synchronous buck conversion working principles ensures efficient power delivery and adjustable current limit protection helps protect the system from damage from excessive load current.
