Triple Output Power Supply DC/DC Converter for TFT-LCD
The XC9516 series can supply power to three different rails of TFT-LCD panels thanks to an integrated step-up DC/DC converter for a source driver, as well as positive and negative charge pumps for a gate driver.
The XC9516 can operate with input voltages between 2.5V and 5.5V. The output voltage of the step-up DC/DC converter can be set between 5.5V and 19V by using two external resistors.
The switching frequency can be adjusted between 300kHz and 1.2MHz, thus permitting to choose between high efficiency (at lower switching frequencies) and low form factor (at higher switching frequencies).
The XC9516 power-up sequencing can be configured in two different ways:
• Input Voltage: 2.5V ~ 5.5V
• Output Voltage: 5.5V ~ 19V
• Switching Frequency: 300kHz ~ 1.2MHz
• Output Current: 500mA
• PWM Switching Control
