XC9133 Datasheet Step-up DC/dc Converter-led Backlight Driver

Manufacturer: Torex Semiconductor

Overview: XC9133 Series Step-Up DC/DC Converter-LED Backlight Driver ETR0413-005a.

General Description

The XC9133 series is a fixed frequency, constant current step-up DC/DC converter which is optimized for LED backlight applications in mobile phones, PDAs and digital cameras.

Output voltage of up to 17.5V is possible so that four white LEDs can be driven in series.

Since the LED current is set by only one external resistor, all white LEDs placed in series can be turned on at the same time.

Key Features

  • Input Voltage Range : 2.5V ~ 6.0V Output Voltage Range : Up to 17.5V externally set-up Reference voltage 0.2V +5% Oscillation Frequency : 1.0MHz±20% ON Resistance : 2.4Ω High Efficiency : 85% 3 white LEDs in series Control VIN=3.6V, ILED=20mA : PWM control Stand-by Current Output Capacitor : ISTB=1.0μA (MAX. ) : 0.22μF, ceramic Lx Limit Current : 360mA（TYP. ） Lx Overvoltage Limit : 19V (TYP. ) Operating Ambient Temperature : -40℃～+85℃ Packages : SOT-25 Environmentally Friendly :.
