Overview
The R1211D100A-TR-FE is a PWM step-up DC/DC controller IC manufactured by Nisshinbo Micro Devices. It operates within an input voltage range of 2.5 V to 6 V and utilizes voltage mode control for efficient power conversion. The device supports a switching frequency of 700 kHz, enabling compact passive component selection. It provides a single output channel and functions reliably across an extended temperature range from -40°C to +85°C. The component is housed in a compact SON-6 package measuring 2.6x1.6 mm, suitable for space-constrained applications.
Feature Summary
- Integrates voltage mode control for stable step-up regulation
- Supports high-frequency operation at 700 kHz
- Features a compact SON-6 surface-mount package
Applications
- Portable electronic devices requiring battery-powered boost conversion
- White LED backlighting driver circuits
- General-purpose DC/DC power supply modules
Procurement Notes
Verify the specific suffix 'TR-FE' against official datasheets to confirm reel packaging and lead-free compliance status. Ensure the ordering code matches the exact voltage mode control variant. Cross-reference the SON-6 footprint dimensions with PCB layout requirements. Confirm RoHS directive adherence through manufacturer documentation prior to procurement.
Selection Notes
Select this component when a dedicated controller is required rather than an integrated switch regulator. The 700 kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that external MOSFET selection aligns with the controller's drive capabilities. Consider the 2.5 V minimum input voltage for compatibility with single-cell lithium-ion batteries.
Part Context
This part belongs to the R1211 series of switching controllers designed for boost converter topologies. It complements other Nisshinbo PMIC solutions by providing a flexible control interface for custom power stages. The series targets applications needing efficient voltage step-up without the complexity of digital control interfaces.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Evaluate functional equivalents based on input voltage range, switching frequency, and package compatibility.
