NCP1501DMR2

Overview

The NCP1501DMR2 is a dual-mode PWM/linear buck converter manufactured by onsemi. It integrates a high-efficiency switching regulator with a linear regulator to optimize performance across varying load conditions. The device operates from an input voltage range of 3V to 18V, providing a regulated output adjustable from 1.2V to 15V. It features a fixed switching frequency of 500kHz and supports output currents up to 1A in switching mode. The component is housed in an 8-MSOP package and is designed for applications requiring efficient power conversion with low noise characteristics.

Feature Summary

• Dual-mode operation combining PWM switching and linear regulation for enhanced efficiency at light loads
• Integrated high-side MOSFET switch eliminates external component requirements
• Fixed 500kHz switching frequency allows for compact passive component selection
• Adjustable output voltage capability via external resistor network

Applications

• Point-of-load regulation for embedded systems
• Power supply stages for industrial control equipment
• Voltage regulation for communication modules
• Battery-powered devices requiring extended runtime

Procurement Notes

Verify the specific suffix 'G' for RoHS compliance status as datasheets may vary. Confirm the package type matches the design footprint, as MSOP dimensions are critical for PCB layout. Ensure input voltage ratings align with system specifications to prevent overvoltage damage. Check for updated revision levels in the latest manufacturer documentation before finalizing procurement.

Selection Notes

Select this component when high efficiency at both heavy and light loads is required without complex external control loops. It is suitable for designs where board space is limited due to the integrated switch and minimal external parts. Consider the thermal performance of the MSOP package under maximum load conditions. Verify that the input voltage range covers the full operational spectrum of the power source.

Part Context

The NCP1501 series belongs to onsemi's portfolio of high-efficiency DC-DC converters. It is part of the broader NCP15xx family designed for versatile power management solutions. The DMR2 designation indicates the specific tape-and-reel packaging variant within the MSOP-8 form factor. This series targets applications needing reliable, compact power regulation with simplified design implementation.

Replacement Considerations

Direct substitutes include other dual-mode buck converters from onsemi such as the NCP1500 series if pin compatibility is required. Cross-reference with similar offerings from other manufacturers like Texas Instruments or Analog Devices only if electrical parameters and pinouts match exactly. Verify thermal dissipation capabilities when replacing with alternative packages.
