P9120-00NBGI8

Voltage Regulators - DC DC Switching Regulators Overview

The P9120-00NBGI8 is a programmable triple-channel power management IC from Renesas Electronics, part of the IDTP9120 series. It integrates three step-down converters with built-in FETs to generate multiple voltage rails from a single input. The device supports an input voltage range of 2.7 V to 5.5 V and delivers output currents of 2 A for Buck1, 2 A for Buck2, and 3 A for Buck3. Factory-programmable output voltages span 0.8 V to 3.4 V. It operates at a switching frequency of 2 MHz and functions within an industrial temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized Renesas distributors. Confirm package integrity upon receipt, as the NBGI8 suffix indicates tape-and-reel packaging. Ensure storage conditions comply with moisture sensitivity level specifications before reflow soldering. Cross-reference datasheet revisions to confirm pinout compatibility with existing designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing systems requiring three isolated or sequenced voltage rails from a single input source. It is suitable for applications demanding high efficiency under light loads due to sleep mode support. Consider the 24-lead QFN package constraints for thermal management. Verify that the factory-programmed voltage settings meet specific rail requirements, as field adjustment may not be possible.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the IDT P9120 family of programmable PMICs, now integrated into Renesas Electronics' portfolio following acquisition. The NBGI8 variant specifically denotes the tape-and-reel packaging format, distinct from tray-packaged versions. It serves as a compact solution for replacing discrete regulator networks in space-constrained PCB layouts.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for updated Renesas part numbers such as P9120-00NBGI8 if available. Evaluate alternative triple-channel PMICs from other manufacturers only if pin-to-pin compatibility and electrical parameters match exactly.
