Component Benefits

Modern electronic designs often require high output voltages from extremely small power sources. The AST Transformer is specifically engineered to bridge this gap, offering a "Value-Added" solution that eliminates the need for bulky power supplies or multiple batteries.

  • Ultra-Compact Footprint: Miniature design allows for seamless integration into small PCB layouts, such as retail hang-tags.

  • High Voltage Gain: Capable of stepping up a 1.5V input to a 20V minimum output to drive high-impedance loads.

  • Optimized Efficiency: Low core losses ensure that battery life is preserved, even during high-output alarm cycles.

  • Custom Winding Ratios: ISL can tailor the primary-to-secondary ratio to meet specific voltage requirements without increasing component size.

  • Continuous Source Support: Available as a long-term manufacturing solution to prevent line stoppages due to component obsolescence.
