Key Features

  • Dual-mode constant-voltage and constant-current (CV/CC) regulation loop in a single 8-pin SOP package for compact charger designs
  • Precision internal voltage reference enables accurate output voltage and current setpoints with minimal external resistor tuning
  • Optimized for flyback and forward converter topologies used in USB chargers, laptop adapters, and battery management systems

Applications

The TSM1011AID serves as the primary control IC in flyback-topology battery charger adapters requiring tight CV/CC regulation for lithium-ion, lithium-polymer, or lead-acid cell packs. Its dual regulation loop switches cleanly between constant-current charging during bulk phase and constant-voltage charging during absorption phase, reducing external component count in 5 W to 30 W adapter designs. The 8-pin SOP footprint allows integration into compact USB charger PCBs and power-bank modules where board space is at a premium.

Frequently Asked Questions

What regulation modes does the TSM1011AID support for battery charging applications?

The TSM1011AID supports both constant-voltage (CV) and constant-current (CC) regulation modes, enabling it to manage the full charge cycle of lithium-ion or lead-acid batteries — delivering up to the programmed current limit during bulk charging and maintaining the target voltage once the battery is nearly full.

Which converter topologies is the TSM1011AID designed to control, and what power range is typical?

The TSM1011AID is optimized for flyback and forward converter topologies and is typically used in charger adapters rated from 5 W to 30 W, covering USB wall chargers, laptop power bricks, and industrial battery management units in its 8-pin SOP package.

How does the TSM1011AID set the output voltage and current limits in a charger design?

Output voltage and current thresholds are programmed using external resistor dividers connected to the feedback and current-sense pins; the precision internal reference (typically ±1% or better) of the TSM1011AID ensures that both CV and CC setpoints remain stable across temperature and input voltage variations.

What package does the TSM1011AID use and how does it aid PCB layout in a compact charger module?

The TSM1011AID is housed in an 8-pin SOP package with 1.27 mm pitch and a body width of approximately 3.9 mm, fitting comfortably on single-layer charger PCBs and enabling automated SMT reflow assembly in high-volume USB adapter or power-bank production lines.
