NJU6048F-TE1

Overview

The NJU6048F-TE1 is a DC-DC step-up (boost) regulator IC manufactured by Nisshinbo Micro Devices Inc., designed specifically for LED driving applications. It features a single output channel capable of delivering up to 20mA of output current, with a maximum output voltage of 18V. The device supports PWM dimming control and is housed in an SC-74A (SOT-753) surface-mount package. This component integrates power management functions to regulate LED brightness efficiently within compact electronic designs.

Feature Summary

• Integrated DC-DC step-up regulator topology optimized for LED driving circuits
• Supports Pulse Width Modulation (PWM) dimming for precise brightness control
• Single-channel output configuration with defined current and voltage limits

Applications

• LED lighting systems requiring regulated boost conversion
• Portable devices utilizing PWM-controlled LED indicators or displays
• Compact electronic modules needing integrated power regulation for light sources

Procurement Notes

Verify the specific package variant, as SOT-753 and SC-74A are often used interchangeably for this footprint. Confirm that the application requires a fixed boost regulator rather than a programmable one. Ensure compatibility with the intended PWM dimming frequency range specified in the official datasheet. Check for any required external components such as inductors or capacitors listed in the reference design.

Selection Notes

Select this component when a dedicated, low-pin-count boost solution for LEDs is required. It is suitable for applications where space is limited due to its small SC-74A package. Consider it if the design demands simple PWM dimming integration without complex microcontroller interfacing for power regulation. Evaluate if the 20mA output current meets the specific LED array requirements.
