Toshiba launches photocoupler with UVLO function for digitally controlled switching power supplies and IPM drives

Toshiba Electronics Europe has launched a ‘high-speed’ IC-Photocoupler for MOSFET gate signal insulation. The TLP2735 is Toshiba’s first photocoupler to incorporate an under voltage lockout (UVLO) function with hysteresis.

According to Toshiba, UVLO reduces the photocouplers susceptibility to noise that is often generated in power supply cables and can prevent malfunctions at switch on.

The operating power supply voltage in the output side covers the 9 to 20V range, which Toshiba says makes it suitable for IPM input insulation.

The TLP2735 is designed to offer a short propagation delay of 100ns (max) and a data transfer rate of 10Mbps and has an operating temperature range of -40 to 125°C.
