POWER PRODUCTS

The TF12A is a low power primary switcher best suitable for Off-line SMPS battery charger adapters, auxiliary power supplies for industrial systems and standby power supplies for TVs or monitors . It consists of a dedicated current mode PWM controller and a high-voltage Power MOSFET.
The TF12A operates at fixed 60 kHz switching frequency. Its control circuitry provides large VDD range desired in applications in which auxiliary power supply changes are expected. It also provides over-voltage, over-current and over- temperature protection. The TF12A is a fast, low power, primary switcher for
topology power supplies.

 

The TF2110 and TF2113 are high voltage, high-speed MOSFET and IGBT drivers with independent high-side and low-side outputs. The high-side driver features floating supply for operation at up to 500V / 600V.
