Key Features

  • Dual-loop constant voltage and constant current control enables precise charging profiles for Li-ion and NiMH batteries without external op-amps
  • Compatible with isolated flyback and forward converter topologies, simplifying charger and adapter designs requiring tight output regulation
  • Compact SOP-8 package minimizes PCB area while providing all necessary control functions for cost-effective adapter and charger solutions

Applications

TSM1011ID is designed for use in battery charger ICs, AC/DC adapters, and power supply units where both output voltage and current must be regulated independently. It is well-suited for consumer electronics chargers, industrial power supplies, and medical-grade adapter designs demanding accurate CC/CV profiles with minimal component count.

Frequently Asked Questions

How does TSM1011ID maintain constant current during the bulk charging phase of a Li-ion battery?

TSM1011ID regulates output current by sensing the voltage across a shunt resistor on the secondary side, typically 0.1 Ω to 0.5 Ω, and adjusting the PWM duty cycle via the feedback loop. This holds charging current within ±5% of the set point across input voltage ranges of 85 V to 265 V AC.

What converter topologies are compatible with TSM1011ID, and what output power levels can it manage?

TSM1011ID works with isolated flyback and forward converter topologies commonly used in adapters up to 30 W to 65 W. Its optocoupler-compatible feedback input allows isolated designs where the SOP-8 package on the primary side interfaces with the secondary-side voltage and current sense network.

For a 5 V, 2 A USB charger design, how many external components does TSM1011ID require compared to a discrete solution?

TSM1011ID integrates the error amplifier and reference for both CV and CC loops, requiring only 6 to 8 passive components such as resistors and capacitors external to the SOP-8 package. A comparable discrete design typically needs 15 or more components, so TSM1011ID reduces BOM count by roughly 50% for the same 5 V / 2 A output specification.
