ADP5050ACPZ-R7

Voltage Regulators - Linear + Switching Overview

The ADP5050ACPZ-R7 is a five-channel integrated power management IC featuring four high-performance synchronous buck regulators and one low-dropout (LDO) linear regulator. It operates with an input voltage range of 4.5 V to 15 V and provides output accuracy of ±1.5% over the full temperature range. The device integrates high-side MOSFETs on Channels 1 and 2, allowing external NFET usage for currents up to 4 A per channel, while Channels 3 and 4 deliver 1.2 A internally. The LDO supports 200 mA output. Switching frequencies are adjustable from 250 kHz to 1.4 MHz, and the unit includes an I2C interface for configuration.

Voltage Regulators - Linear + Switching Procurement Notes

Verify the specific suffix R7 indicates tape and reel packaging when ordering. Confirm that the ACPZ designation corresponds to the required lead-free RoHS-compliant LFCSP package variant. Ensure compatibility with the intended I2C address and switching frequency settings before finalizing procurement specifications.

Voltage Regulators - Linear + Switching Selection Notes

Select this component when board space is limited and multiple power rails are needed from a single source. It is suitable for applications requiring high efficiency via synchronous rectification and precise voltage regulation. Consider the maximum current requirements of each channel, noting that Channels 1 and 2 support higher currents with external FETs compared to the internal integration of Channels 3 and 4.

Voltage Regulators - Linear + Switching Part Context

This part belongs to the ADP5050 series of multi-channel PMICs designed by Analog Devices. It is functionally similar to the ADP5052 but differs in specific channel configurations and capabilities. The device is housed in a 48-lead LFCSP package, offering a compact solution for complex power distribution networks in space-constrained electronic designs.

Voltage Regulators - Linear + Switching Replacement Considerations

The ADP5050ACPZ-R7 is parameter-equivalent to the ADP5052ACPZ-R7. Verify pin-to-pin compatibility and specific channel current ratings before substitution, as differences may exist in internal MOSFET integration or control logic between these variants.
