Overview
The TSM1051CD is a highly integrated constant voltage and constant current controller designed for switch-mode power supply applications, specifically targeting battery chargers and adapters. It operates within an input voltage range of 4.5V to 32V and provides a fixed output reference of 1.24V. The device supports a maximum output current of 10 mA and draws a supply current of 2 mA. It is housed in an 8-SOIC package with a width of 3.90 mm and functions reliably across a temperature range of -20°C to 80°C.
Feature Summary
- Provides integrated constant voltage and constant current control modes for power supply regulation
- Designed as a compact solution for switch-mode power supply architectures
- Supports operation within a wide input voltage range suitable for various adapter standards
Applications
- Battery charger systems requiring precise CV/CC regulation
- AC-DC adapter designs
- Switch-mode power supply control circuits
Procurement Notes
Verify the exact part number suffix against official STMicroelectronics documentation to ensure correct package and temperature grade specifications. Confirm that the 8-SOIC package variant matches your PCB footprint requirements. Check for RoHS compliance status relevant to your manufacturing region regulations before finalizing procurement orders.
Selection Notes
Select this component when a dedicated IC is required for managing both constant voltage and constant current phases in a single-stage or two-stage SMPS design. Ensure the 10 mA output capability meets the reference circuit demands. Verify that the 8-SOIC thermal dissipation characteristics are sufficient for the intended operating environment without additional heatsinking.
Part Context
The TSM1051CD belongs to the TSM1051 family of power management integrated circuits from STMicroelectronics. This series focuses on providing efficient control solutions for secondary-side or primary-side switching applications where space constraints favor surface-mount packages like the 8-SOIC over larger alternatives.
Replacement Considerations
Consult official STMicroelectronics substitution guides for verified equivalents. Generic replacements may not match the specific CV/CC control algorithms or pinout configurations required by existing board layouts.
