RX-8025SA 描述
The external bootstrap capacitor is necessary to achieve the fastest gate rise times. The bootstrap capacitor (C3) supplies additional current at a higher voltage to the gate drive regulator as the MOSFET is switched on. When the MOSFET is off, the gate drive regulator voltage is applied to the boost capacitor . As the MOSFET turns on, the MOSFET source-to-ground voltage increases. The increas- ing source voltage is added to the voltage across the capaci- tor for a voltage doubling effect. Gate Drive Regulator
RX-8025SA 特点
The RX-8025SA has 8-bit binary down counter and D-type Flip Flop. The counter can set up to max 256 counts and synchronous preset (SPE) input can preset the data. When the count value is 0, the next clock pulse presets the data to invert the output. D-type Flip Flop takes the counter output as clock pulse, whose data is transferred to output at the rise edge. It is applied to generate AC signal for STN type liquid crystal and general-use divider.
RX-8025SA 应用
Unless noted otherwise, all measurements are made with the filter installed in the specified test fixture that is connected to a 50Ω test system with VSWR 1.2:1. The test fixture L and C are adjusted for minimum insertion loss at the filter center frequency, fC. Note that insertion loss, bandwidth, and passband shape are dependent on the impedance matching component values and quality.
