MAS6230 is a high efficiency synchronous buck-boost DC/DC converter IC with integrated switches. This makes external power switches unnecessary and offers a small size power supply solution for USB-PD car charger applications. Wide input voltage range from 7V to 36V allows using MAS6230 in both 12V and 24V car battery systems and covers wide range of industrial applications. The output voltage is adjustable from 4V to 20V by two external resistors. There are two control pins which make it possible to select output voltage from four voltage options such as 5V, 9V, 15V and 20V.
The buck-boost DC/DC converter achieves over 90% efficiencies and can delivery up to 60W output power. The maximum output current is 3A in buck mode. MAS6230 integrates over temperature (OTP) and output overvoltage protection (OVP) circuitry to prevent damage under fault conditions. The device is available in a thin 7x7x0.75 mm 48-lead QFN package.
