KTD3112 overview
KTD3112 is a component documented by Kinetic Technologies. The PDF description identifies it as "High Efficiency Boost 2P6S/3P6S LED Driver October 2015 - Revision 04a." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.
Datasheet snapshot

- Datasheet length: 13 Pages
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.
- 20mA/25mA current per channel 1.5% Typ.
- current matching PWM dimming with < 0.3µs rise/fall time Low quiescent current LED open/short protection 25V LED open-circuit (OVP) threshold Cycle-by-cycle inductor current limit < 1µA shutdown current Pb-free Packages: TQFN.
- It is a highly integrated step up DC-DC converter with input voltage range from 2.7V to 5.5V, accommodating 1-cell lithium ion battery or 5V regulated supply.
- KTD3112/3 integrates a 30V Power MOSFET as well as compensation and soft start circuitry, which results in a simpler and smaller solution with much fewer external components.
- High switching frequency ( 800kHz) allows the use of a smaller sized inductor and capacitor.
- Two regulated current sinks in KTD3112 and three sinks in KTD3113 provide per channel 20mA/25mA (max.) factory programmed current .
- With a 25V OVP, each string can connect up to six LEDs in series, for a total of 12 or 18 LEDs in KTD3112 and KTD3113 respectively.

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.
