R1225N602K-TR-FE

Overview

The R1225N602K-TR-FE is a positive output step-down DC-DC controller IC manufactured by Nisshinbo Micro Devices Inc. It supports an input voltage range up to 18.5V and utilizes PWM/VFM control modes for efficient power conversion. The component is housed in a SOT-23-6 package, designed for compact surface-mount applications requiring regulated voltage stepping.

Feature Summary

Supports high input voltage up to 18.5V
Integrates PWM and VFM control modes
Configured as a positive buck regulator

Applications

Battery-powered portable electronics
Industrial control systems
Automotive electronic modules

Procurement Notes

Verify the specific suffix 'K' against the official datasheet to confirm pinout and thermal characteristics. Ensure the ordering quantity aligns with manufacturer packaging standards. Cross-reference the Mouser number 848-R1225N602K-TR-FE for accurate supply chain tracking.

Selection Notes

Select this model when an 18.5V input tolerance is required alongside space-constrained designs. The SOT-23-6 footprint suits low-profile boards. Confirm that external components match the PWM/VFM switching requirements for optimal efficiency.

Part Context

This part belongs to the R1225N series of DC-DC controllers from Nisshinbo Micro Devices. It complements other variants like R1225N162D and R1225N332B, offering distinct input voltage handling and control logic within the same product family architecture.

Replacement Considerations

Direct substitutes include R1225N162D-TR-FE and R1225N332B-TR-FE. Verify compatibility regarding input voltage limits and control mode differences before swapping.
