Photocoupler with UVLO for switching power supplies controlled digitally and IPM drives: TLP2735

Product News 2017-11

SO6L

"TLP2735" is Toshiba Electric Device & Storage Corporation's first high speed IC photocoupler, which incorporates UVLO[1] function, for MOSFET gate signal insulation.
By adopting UVLO[1] function, the photocoupler has little influence from noise like that generated in power supply line, and can prevent malfunction when the equipment turns on.
With an isolation voltage of 5 kVrms (min) between the input and output, as well as conformity with the IEC60747-5-5[2] photocoupler safety standard, TLP2735 is also suitable for applications requiring high insulation performance.
The operating power supply voltage in the output side is 9 V to 20 V, specifications suited to MOSFET gate voltages, and the propagation delay time is 100 ns (max), fast for a photocoupler designed for MOS gate insulation. As its power supply voltage is high, it can also be used for Intelligent Power Module (IPM) input insulation.
Simply adding a buffer circuit to the subsequent stage of TLP2735, a MOSFET insulation gate drive circuit can be implemented. In addition, with its operating temperatures of -40°C to 125°C, it can also be used in a high temperature environment.
 

The latest Gartner market report recognizes Toshiba as the leading manufacturer of optocouplers by sales in 2015 and 2016, with 23 % of sale-based market share in CY2016. (Source: Gartner, Inc. "Market Share: Semiconductor Devices and Applications Worldwide 2016" 30 March, 2017)
Toshiba Electronic Devices & Storage Corporation will continue to develop products that meet the needs of customers by promoting the development of a diverse portfolio of photocouplers and photorelays tailored to market trends.
