Overview
The SC450ITSTRT is a dual-phase power supply controller manufactured by Semtech. It operates as a high-performance hysteretic PWM controller with two outputs and an open-drain output type. The device supports a non-isolated topology and functions within a 30 V operating supply voltage range. Key electrical specifications include a minimum output voltage of 1.708 V and a maximum output current capability of 32 A. It is housed in a TSSOP-38 surface-mount package.
Feature Summary
- Dual-phase control architecture for synchronized power delivery
- Hysteretic PWM control method for dynamic response
- Open-drain output configuration for flexible interfacing
Applications
- High-current multi-rail server power systems
- Telecommunications infrastructure power supplies
- Industrial equipment requiring dual-phase regulation
Procurement Notes
This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution channels indicate that Mouser does not currently stock this item in many regions. Buyers must verify active obsolescence status and availability through authorized distributors or secondary markets before committing to procurement plans.
Selection Notes
Engineers should evaluate alternative components from the same family or newer generations due to the discontinued status of this specific part number. Verify that replacement controllers match the required 32 A output current capacity and TSSOP-38 footprint constraints while ensuring compatibility with existing hysteretic control designs.
Part Context
The SC450 series represents Semtech's line of high-performance switching controllers designed for demanding power management applications. This specific model focuses on dual-phase regulation, distinguishing it from single-phase variants like the SC4508AMLTRT or quad-output models such as the SC2453ITSTRT within the broader portfolio.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation.
