XC9119D10A Series 1MHz, PWM Controlled, Step-Up DC,DC Converter, Ceramic Capacitor Compatible
●GENERAL DESCRIPTION
■The XC9119D10A series is 1MHz, PWM controlled step-up DC/DC converter, designed to allow the use of ceramic capacitors. With a built-in 2.0Ω switching transistor, the XC9119D10A series can easily provide a step-up operation by using only a coil, a diode, a capacitor, and a resistor, connected externally.
■Since output voltage up to 19.5V (Maximum Lx operating voltage: 20V) can be derived with reference voltage supply of 1.0V (±2.0%) and external components, the series can easily supply high voltage for various general-purpose power supplies, LCD panels and organic EL displays.
■With a high switching frequency of 1.0MHz, a low profile and small board area solution can be achieved using a chip coil and an ultra small ceramic output capacitor.
■With the current limit function (400mA (TYP.): VDD=3.6V), a peak current, which flows through built-in driver transistors can be limited. Soft-start time can be adjusted by external resistors and capacitors. The stand-by function enables the output to be turned off (CE ’L’), that is, the supply current will be less than 1.0μA.
