File format: PDF Size:94 KB

The BTA/BTB12 and T12 triac series are suitable for general purpose AC switching. They can be used as an ON/OFF function in applications such as static relays, heating regulation, induction motor starting circuits. or for phase control operation in light dimmers, motor speed controllers. The snubberless versions are specially recommended for use on inductive loads, thanks to their high commutation performances. Logic level versions are designed to interface directly with low power drivers such as microcontrollers. The BTA series provides voltage insulated tab (rated at 2500V RMS) complying with UL standards.

The ST1S15 is a high efficiency miniaturized step-down converter able to provide 500 mA output current from an input voltage from 2.3 to 5.5. This converter is specifically designed for applications where high efficiency and small application area are the key factors. With an output voltage as low as 0.6 V the device supports low voltage DSPs and processors core supply. Due to the 6 MHz switching frequency the ST1S15 can use nominal values of 470 nH for the inductor and 4.7 µF for the output capacitor, providing, at the same time, very good performance in terms of load and line transients. It is possible to select a PFM mode for high efficiency under light load conditions or PWM mode for tight regulation and best dynamic performance. Short-circuit and thermal protection are included.
