HIGH SIDE SWITCH WITH INPUT OVERVOLTAGE AND OVERCURRENT PROTECTION

The project here is a 48V protected, high side switch designed to switch a 5A output load from input voltages from 8V to 48V. The circuit helps the user to easily ON/OFF the high current and voltage load with over-voltage lockout and over-current protection. The wide input range and low shutdown current (1μA typical) make it suitable for automotive, industrial, […]

XDL601/02 – 5.5V, 1.5A HI-SAT COT SYNCHRONOUS BUCK MICRO DC/DC WITH INTEGRATED COIL

The XDL601/02 are ultra-small, 1.5A, synchronous step-down Micro DC/DC Converters with integrated inductor and high-speed transient response. The superfast load transient performance is due to Torex’s innovative Hi-SAT COT control method, which, when compared to standard Constant On-Time (COT) control also provides less fluctuation in oscillation frequency against load and input voltage. The XDL601/02 total solution size is only
