NJW4750MHHT1-TE1

Overview

The NJW4750MHHT1-TE1 is a quad-channel power management IC from Nisshinbo Micro Devices. It integrates three synchronous step-down DC-DC converters and one low-dropout linear regulator, providing four regulated outputs. The switching regulators operate at frequencies ranging from 280kHz to 2.4MHz. The device supports a supply voltage of up to 40V. Output currents are specified as 1.2A for the primary channels and 0.6A for secondary channels.

Feature Summary

• Integrates multiple regulation types including synchronous buck and LDO in a single package
• Features adjustable switching frequency range for optimized efficiency and component size
• Provides high input voltage tolerance suitable for various bus architectures

Applications

• Portable electronic devices requiring multiple voltage rails
• Industrial control systems with mixed analog and digital power needs
• Communication equipment utilizing synchronized power sequencing

Procurement Notes

Verify the complete part number including suffixes against official datasheets to ensure correct pinout and thermal characteristics. Confirm availability status as distribution channels may vary. Check RoHS compliance documentation for specific regional regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact solution combining switching and linear regulation is required. Ensure the application load current does not exceed the 1.2A or 0.6A limits per channel. Verify that the operating frequency range aligns with external inductor selection and EMI constraints for the target design.

Part Context

This part belongs to the NJW4750 series of multi-output PMICs. It consolidates power management functions typically handled by discrete components. The integration reduces board space and simplifies design complexity for systems needing stable power delivery across multiple domains.

Replacement Considerations

Direct substitutes include other quad-channel PMICs from Nisshinbo such as the NJW4750M variant. Cross-reference pin compatibility and electrical specifications carefully. Alternative manufacturers may offer similar functionality but require verification of thermal performance and control interface differences.
