XC9119D10A Series
ETR0408_008
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 2.0 Ω 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.): V DD =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 1.0 ? A.
