ADP2386ACPZN-R7

The ADP2386ACPZN-R7 is a synchronous step-down DC-to-DC regulator from Analog Devices Inc. It features integrated high-side and synchronous rectification MOSFETs with low on-resistance values of 44mΩ and 11mΩ, respectively, providing high efficiency for power conversion applications.

This device operates using a peak current mode, constant frequency pulse width modulation (PWM) control scheme, which ensures excellent stability and transient response. The switching frequency of the ADP2386ACPZN-R7 can be programmed within a range of 200 kHz to 1.4 MHz, allowing for minimization of system noise and the synchronization of switching frequencies with external clocks.

The ADP2386ACPZN-R7 requires minimal external components and can operate with an input voltage range of 4.5 V to 20 V. The output voltage is adjustable within a range of 0.6 V to 90% of the input voltage, and it can provide a continuous output current of up to 6 A. When disabled, each IC consumes minimal current from the input source, exceeding 110 μA in standby mode.

This regulator is designed for applications requiring high efficiency and design flexibility. It offers external compensation and an adjustable soft-start function, providing additional design flexibility. The power good and enable inputs ensure simple and reliable output power sequencing. Other key features include under-voltage lockout (UVLO), over-voltage protection (OVP), over-current protection (OCP), short-circuit protection (SCP), and thermal shutdown (TSD).

The ADP2386ACPZN-R7 operates over a junction temperature range of -40°C to +125°C and is available in a compact 4 mm × 4 mm LFCSP package with 24 pins. It is suitable for a wide range of applications, including communication infrastructure, networking and servers, industrial and instrumentation equipment, healthcare systems, intermediate power rail conversion, and DC-DC point-of-load applications.

In summary, the ADP2386ACPZN-R7 is a highly efficient, flexible, and reliable synchronous step-down DC-to-DC regulator suitable for a variety of power conversion applications.
