Frequently Asked Questions
What is the input voltage range of the TLS1242N?
The TLS1242N operates with an input voltage range from 12V minimum to 20V maximum, with a nominal input of 15V. This range is appropriate for use in offline power factor correction converter circuits powered from standard AC mains via a rectifier stage.
What control technique does the TLS1242N use for power factor correction?
The TLS1242N uses current-mode pulse width modulation (PWM) control to perform power factor correction. Current-mode control provides inherent cycle-by-cycle current limiting, improved transient response, and simpler loop compensation compared to voltage-mode PFC controllers.
What package and pin count does the TLS1242N come in?
The TLS1242N is housed in a 20-pin PDIP (Plastic Dual In-Line Package), with JESD-30 code R-PDIP-T20. The through-hole DIP format is ideal for prototyping, evaluation boards, and replacement of components in legacy industrial power supply designs.
Is the TLS1242N suitable for meeting power quality standards like IEC 61000-3-2?
Yes, the TLS1242N is specifically designed for power factor correction in AC-DC converters, which helps achieve compliance with power quality standards such as IEC 61000-3-2. By correcting power factor and reducing harmonic current draw, it enables power supply designs to meet regulatory requirements in many global markets.
