A8169-020
Key Features
- The A8169-020 variable frequency step-up Converter
- Up to 19V Output Voltage drives white LEDs with a constant current to provide
- Wide Operation Range: 2V to 6V backlight in cell phones, PDAs, and other hand-held
- Maximum 3MHz Operating Frequency devices. It features allowing series connection of the
- PWM Dimming Control white LEDs so that the LED currents are identical for
- Shutdown Current <1uA uniform brightness. An enable input can be pulsed
- Current Limit Cycle-by-Cycle repeatedly to adjust LEDs brightness. The fast 3MHz
- Low Current Sense Threshold: 200mV operation frequency allows for smaller capacitor and
- 19V Over Output Voltage Protection inductor. Fault condition protection uses cycle-by cycle
- Available in SOT-26 package current limiting to sense maximum inductor current and over-voltage protection. The 0.2V low reference voltage
