Si3500 - Silicon Laboratories

Si3500 50V INPUT DC TO DC CONVERTER

The Si3500 is a highly-integrated, high-voltage (42 to 57 V) input dc-to-dc converter with integrated PWM control and power FET. The output can be adjusted for various applications in the range of 1.8 to 12 VDC. The integrated hot swap switch provides a 2-level current limit for slow charging of the input filter capacitor followed by overcurrent protection a.
