APPLICATIONS
" CD-R / RW, DVD " HDD " PDAs, portable communication modem " Cellular phones " Palmtop computers " Cameras, video recorders ! GENERAL DESCRIPTION
A voltage detector is also built-in. Since the input for the LDO voltage regulator block comes from the input power supply, it is suited for use with various applications. The XC9511 is designed for use with small ceramic capacitors. A choice of three switching frequencies are available, 300 kHz, 600 kHz, and 1.2 MHz. Output voltage settings for the DC/DC and VR are set-up internally in 100mV steps within the range of 0.9V to 4.0V (± 2.0%). For the VD, the range is of 0.9V to 5.0V (± 2.0%). The soft start time of the series is internally set to 5ms. With the builtin U.V.L.O. (Under Voltage Lock Out) function, the internal P-channel driver transistor is forced OFF when input voltage becomes 1.4 V or lower. ! FEATURES
Input Voltage Range : Load Capacitors : 2.4V ~ 6.0V Ceramic Capacitor Compatible (Low ESR Capacitors) VD Function : Detects output voltage from the VDOUT pin while sensing either VDD, DCOUT, or VROUT internally.
