SA6880-S Evaluation Board Users Guide DPD1182 SA6880-S Isolated 3.5 A / 1200 V IGBT Driver Evaluation Board 1. Introduction The SA6880-S is a high performance isolated IGBT/MOSFET driver IC with 3.5 A peak output current capability. The SA6880-S evaluation board is designed to allow testing of two SA6880-S drivers in either a half bridge or a DC/DC synchronous buck configuration. For synchronous buck testing 1200 V / 380 V, a 15 mH inductor and 4.6 F capacitor should be populated. The design was tested as described in this document. It has not been qualified to operate over a wide temperature range. The evaluation board is provided for functional testing and evaluation purposes only. Evaluation board specifications for a synchronous buck configuration: Input voltage: 1200 V Output voltage: 380 V Output current: 0.4 A Operation frequency 20 kHz Duty cycle: 0.34 2.

Open drain active LOW output 6 FAULTB Desaturation (Over-current protection) Fault. Open Drain active LOW output 7 IP Non-inverting driver input. The IP input controls signal for the driver output while IN is set to low. The IGBT/MOSFET is turned on when IP is set to high and IN is set to low, otherwise it is turned off. A minimum pulse width is required to suppress glitches while controlling the IGBT/MOSFET. An internal pull-down resistor ensures that the IGBT/MOSFET is kept in off-state if terminal IP is left unconnected. 8 IN Inverting driver input. IN- control signals for the driver output while IP is set to high. The IGBT/MOSFET is turned on when IN- is set to low, and is turned off when IN- is set to high, while IN is kept high. 9 VNEG High side (HS) negative supply voltage (Ref.
