Low-voltage switching regulator iC-WDB

Applications 5 V resp. 3.3 V supply e.g. from 24 V industrial network Features Input voltage 8 to 36 Vdc Highly efficient down converter Switching transistor and free-wheeling diode integrated Adjustment of the regulator cut-off current with external resistor Integrated 100 kHz oscillator without external components Switching frequency above the audible range Two downstream linear regulators with 200 mA/25mA output current Three different output voltage combinations of 3.3V version available (see Block Diagram) Small residual ripple with low capacitances in the μF range Fault message at overtemperature and undervoltage at current-limited open-collector output Shutdown of switching regulator at overtemperature Internal reference voltages ESD protection Low space requirement with SO8 resp. tiny DFN10 package Option: enhanced temperature range of -40 to 85 °C
