... R2J20654NP Description of Operation The DrMOS multi-chip module incorporates a high-side MOS FET, low-side MOS FET, and MOS-FET driver in a single QFN package. Since the parasitic inductance between each chip is extremely small, the module is highly suitable for use in buck converters to be operated at high frequencies. The control timing between the high-side MOS FET, low- side MOS FET, and driver is optimized so that high efficiency can be obtained at low output-voltage. VCIN & ...

... R2J20654NP DEM Operation (ZCD_EN# = "L" in Light load condition PWM GH GL The PWM input is TTL level and has hysteresis. When the signal route from the control IC is high impedance, the tri- state function turns off the high- and low-side MOS FETs. This function operates when the PWM input signal stays in the input hysteresis window for 150 ns (typ ...
