Beschreibung

Evaluation circuit EVAL-LTC7892-BZ features the LTC®7892. The LTC7892 is a 100V step-up synchronous Gallium Nitride (GaN) field effect transistor (FET) controller optimized in this application with 100V GaN FETs for an operational 9V–36V input range at 500kHz. The EVAL-LTC7892-BZ is specifically designed to drive GaN FETs safely and easily up to 1.4kW power levels through internally optimized bootstrap switches and adaptive time control. Split gate drivers allow for easily adjustable turn-on and turn-off of FETs. Additionally, the IC features low IQ, up to 3MHz programmable/synchronizable switching frequency, spread spectrum, and a small 40-lead (6mm x 6mm) side wettable QFN package. These features allow various applications, including industrial, military, medical, and telecommunications systems.The EVAL-LTC7892-BZ operates from a 9V–36V input voltage range and generates a maximum 48V, 30A output. The LTC7892 has a precision voltage reference that can generate an output voltage with 2% tolerance over the full operating conditions. The EVAL-LTC7892-BZ is set to a 500kHz switching frequency, which results in a small and efficient circuit. The converter achieves over 98% efficiency with 30A load at full operating VIN, with a peak efficiency near 99%.
