Key Features

  • Integrated constant-voltage and constant-current (CV/CC) dual-loop control for accurate battery charger regulation
  • Compact 8-pin SOP8 package with 1.27 mm pitch enabling high-density power supply PCB layouts
  • Designed for adapter and charger topologies with low external component count for BOM cost reduction

Applications

TSM1011AIDT is optimized for flyback and other isolated power supply topologies used in battery chargers for Li-ion and Ni-MH battery packs, as well as compact AC/DC adapters for consumer electronics. Its integrated CV/CC controller simplifies the feedback and regulation circuit design, reducing time-to-market for charger products. The device is also applicable in low-power industrial power supplies requiring precise output voltage and current limiting regulation.

Frequently Asked Questions

Which charging topologies is TSM1011AIDT best suited for in a 5 V / 2 A Li-ion battery charger design?

TSM1011AIDT is optimized for flyback converter topologies where secondary-side constant-voltage and constant-current regulation is needed. In a 5 V / 2 A design, its integrated CV/CC control loops regulate output voltage to within a tight tolerance while limiting peak charge current, covering the complete CC-CV charging profile for Li-ion cells without external op-amps.

How many pins does TSM1011AIDT have, and what package style is used?

TSM1011AIDT is housed in an 8-pin SOP8 package with a 1.27 mm lead pitch in a small outline rectangular body, making it easy to place on compact charger PCBs. The 8-pin count integrates all control, reference, and feedback functions in a minimal footprint, minimizing the total PCB area needed.

Can TSM1011AIDT replace a discrete op-amp and shunt reference circuit in a CV/CC adapter design?

Yes, TSM1011AIDT integrates the voltage reference, error amplifiers, and both CV and CC control loops in a single 8-pin SOP8 IC, directly replacing discrete solutions built around a TL431 shunt reference plus external op-amp. This consolidation typically reduces part count by 4 to 6 components and lowers bill-of-materials cost for adapter production.

For compact adapter designs, how does the SOP8 package of TSM1011AIDT affect PCB space usage compared to DIP solutions?

The SOP8 package of TSM1011AIDT occupies approximately 19.7 mm² of PCB area, roughly 4 times smaller than a DIP-8 package footprint. This compact footprint enables higher power density in adapter PCB layouts, especially important for wall-plug chargers where internal dimensions are tightly constrained.
