New Levels of Power Density
Silicon MOSFETs has used extensively in most power application since 35 years ago that displaced the bipolar transistor. In these 10 years, Gallium Nitride (GaN) is already an established semiconductor material, employed extensively in LED lighting and wireless applications. Now, with GaN FET’s characteristics and process advances (lower Rdson and Qg), the power converter will have the greater efficiency, faster switching frequency and smaller dimension. The GaN will definitely bring the current power solution into next level.
uPI GaN Driver Family
uPI ultra high speed 80V HB driver — uP1966 is designed to effectively to drive both high-side and low-side GaN FETs in half and full-bridge configuration. It integrates the dead-time control circuit, internal boostrap supply and faster propagation delay. Compared to discrete implementations, it’s simple to use, and it brings your power solution to achieve high power density and efficiency with less component counts. The uP1966 has Couple versions version which supports different input source, adjustable dead time control and ultra high frequency application. All versions are available in 12-pin WLCSP package with minimized package inductance.
