Description

The TIDA-00174 reference design is a 4-output isolated Fly-Buck power supply for IGBT gate drive bias. It generates two sets of (+16V: -9V) voltage output with 100mA output current capability. The positive/negtaive bias voltages are used to power the high power IGBT gate drivers: and the design is suitable to support driving IGBTs.This Fly-Buck design  features the LM5017: 7.5-100V wide Vin: 600mA: Constant On-Time (COT): synchronous buck regulator. It provides an easy-to-design and cost effective isolated power solution. The Fly-Buck having the nature of primary side regulation can achieve better regulation and line/load response over other open-loop or aux winding feedback topologies. It is capable of operating from a loosely regulated 24V input (+/-20%). The board comes with plug-in header pins: and it is compatible with the C2000 HV inverter kit.
