3MHZ, VARIABLE FREQUENCY DESCRIPTION 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 APPLICATIONS minimized the power loss across the current sense resistor.
 Compact Back Light Module The converter can operate from 2V to 6V, and capable of  Power Source for LED delivering maximum 250mA output current at 4-LEDs  Constant Current Source application with 3V input voltage.
Quiescent current drawn from power source is as low as 120uA.
All of these ORDERING INFORMATION features make A8169-020 be suitable for the portable devices, which are supplied by a single battery.
Package Type Part Number The A8169-020 is available in SOT-26 Package.
TYPICAL APPLICATION SOT-26 A8169E6R-020 E6 A8169E6VR-020 Note R: Tape & Reel V: Halogen free Package AiT provides all RoHS free products Suffix “ V “ means Halogen free Package REV1.
