Why SOT23-6?
The SOT23-6 package is the industry standard for compact power management ICs. Its 6-pin configuration provides enough I/O for sophisticated control functions (enable, feedback, compensation, soft-start) while maintaining a PCB footprint of just 2.9 × 1.6mm. This makes it the preferred package for:
- Portable and wearable electronics where board space is critical
- LED driver circuits requiring constant current control
- Battery-powered devices needing efficient DC-DC conversion
- IoT modules and sensor nodes with tight power budgets
Key Features
- ✅ 13 model variants available — LED drivers, buck converters, load switches, and LDOs in one product line
- ✅ SOT23-6 SMD package — minimal PCB footprint for space-constrained designs
- ✅ High switching efficiency — TMI series ICs are optimised for low quiescent current and high conversion efficiency
- ✅ 5PCS per pack — cost-effective for prototyping and small production runs
- ✅ New original parts — genuine TMI components, not remarked or counterfeit
Common Applications
- LED strip and panel driver circuits
- Li-ion / LiPo battery charger power stages
- DC-DC step-down (buck) converter modules
- IoT sensor node power management
- Portable device power rails
- Automotive interior LED lighting drivers
- Solar energy harvesting power management
Frequently Asked Questions
Q: How do I select the right TMI model for my application?
A: Refer to the model table above for application guidance. Download the specific datasheet for your chosen model from the TMI (Techcode Microelectronics) website for full electrical specifications, application circuits, and layout guidelines.
Q: Are these genuine TMI parts?
A: Yes. These are new, original TMI series ICs. Each part is marked with the TMI logo and model number on the SOT23-6 body.
Q: Can I hand-solder SOT23-6 packages?
A: Yes, with a fine-tip soldering iron (0.5–1mm tip), flux, and thin solder (0.3–0.5mm). A hot air rework station or reflow oven is recommended for production use.
