Applications listed in the PDF
- Smartphone/Tablet Backlight Brief Description KTD3133 is the ideal power solution for LED backlighting in medium to large size LCD panels. It is a highly integrated step-up DC-DC.
- Data transfer may be initiated only when the bus is not busy.
- During data transfer, the data line must remain stable whenever the clock line is HIGH. Changes in the data line while the clock line is high are interpreted as control signals. A.
- Master generates start condition.
- Master sends 7-bit slave address (0110110 for KTD3133, 0110101 for KTD3133A) and 1-bit data direction ‘0’ for write.
- Slave sends acknowledge if the slave address is matched.
Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- It is a highly integrated step-up DC-DC converter operating with an input voltage from 2.7V to 5.5V, accommodating 1 -cell lithium ion batteries or 5V supply.
- High switching frequency allows the use of a smaller inductor and capacitor.
- Each of the two regulated current sinks can regulate up to 29.8mA in backlight mode.
- With a maximum of 32V at the output of the step-up converter, each string can connect up to 8-LED in series for a 16-LED application.
- For additional flexibi lity, PWM dimming with wide range frequency and duty cycle is included to support Content Adaptive Brightness Control (CABC).
- KTD3133 is available in a RoHS compliant 12-ball 1.19mm x 1.
- 64mm WLCSP or a 16 -lead 3mm x 3mm x 0.75mm Thin-QFN package.

Engineering review checklist
- Verify capacitance tolerance, rated voltage, temperature range and any DC-bias derating.
- Check ESR, ripple-current capability, lifetime and polarity requirements under worst-case conditions.
- Confirm package dimensions, land pattern and reflow or mounting limits for the selected ordering code.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
