Qualified for automotive 36V & 600mA Synchronous Step-Down DC/DC Converters
The XD9704 series are 36V operation synchronous step-down DC/DC converter ICs with a built-in High side driver FET and Low side driver FET. The XD9704/XD9705 series has an operating voltage range of 3.0V to 36.0V, a switching frequency of 2.2MHz, and by utilizing synchronous rectification, delivers stable voltage with high efficiency. The output voltage can be changed from 2.8V to 20.0V using an external resistor, so the same part number can be used for multiple power lines.
By connecting a resistor and capacitor to the EN/SS pin, the soft-start time can be externally adjusted to be longer than the internal soft-start. The power good function also monitors the state of the output voltage. This soft-start external adjustment and power good functions make it easy to configure the power supply sequence. Over-current protection and thermal shutdown are built in as protection function, and it can be used safely.
