1MHz PWM Step-Up DC/DC Converter

This series of 1MHz, PWM controlled step-up DC/DC Converters are designed to allow the use of ceramic capacitors. With built-in 2.0 Ohm switching transistor, a complete XC9119 circuit needs only a small external coil, diode, capacitor and resistors, thus minimising PCB area. The XC9119 is still able to provide output voltages up to 19.5V making it the ideal IC for LCD panel power supplies.

• Operating Voltage Range: 2.5V ~ 6.0V
• Output Voltage Range: ~19.5V (externally set-up with Vref=1.0V±2.0%)
• Oscillation Frequency: 1.0MHz (Accuracy ± 20%)
• High Efficiency: 80% (VDD=3.2V, VOUT=15V)
• Ultra Small Packages: SOT-25, USP-6C
