TLP2735
1. Applications
• Intelligent Power Module Signal Isolation
• Switching Power Supplies
• High-Speed Digital Interfacing for Instrumentation and Control Devices
2. General
The Toshiba TLP2735 consists of high-output GaAℓAs light-emitting diode coupled with a high-gain, high-speed
photo detector. It is housed in a thin SO6L package of 2.3 mm (max). The TLP2735 has guaranteed the isolation
voltage 5 kVrms and compliant with international safety standards for reinforced insulation. This product can
operate in power supply voltage 9 V to 15 V with the maximum operating temperature of 125 . Since TLP2735
has UVLO function, it can prevent false operation during VDD starting up or under low voltage condition. The
detector has a totem-pole output stage with current sourcing and sinking capabilities. The TLP2735 has an
internal Faraday shield that provides a guaranteed common-mode transient immunity of ±25 kV/µs.
