STEP-UP DC/DC CONVERTER

DESCRIPTION

FEATURES

The A8169-020 Series is a fixed frequency,

constant current step-up DC/DC converter ideal for

driving LEDs used in high-definition screen

backlight LED driver etc. The highest output voltage

is 24V, the input voltage of 3.6V can drive 3 series,

17 in parallel, a total of 51 LED. The internal circuit

integrated overvoltage protection circuit and

temperature protection circuit, and the brightness of

the LEDs can be controlled with a PWM signal. The

internal circuit integrates a large pipes of 0.2 ohms.



Input voltage range: 3.0V~6.0V

Output voltage range: up to 24V

Oscillation frequency: 1.2MHz±20%

Efficiency: 88%

Control mode: PWM control

Stand-by Current: I_STB=1.0μA(MAX)

Load capacitor: 10μF,ceramic

Available in SOT-26 Package

APPLICATION

The A8169-020 is available in SOT-26 package.

Note

AiT provides all RoHS products

The application of single section lithium electricity power supply

Caution: The value of the resistance named R_LED: R_LED=V_FB/(I_LED*n);

V_FBis the voltage of the FB pin; I_LEDis the current of LED and equal

to 20mA usually. n is the number of LEDs in the circuit in parallel.
