Overview
The KTD3156BEFJ-TR is a current-regulated step-up converter designed for LED backlighting. It integrates six current sinks to drive up to 60 LEDs in a 10S6P configuration. The device operates with an input voltage range of 2.7V to 5.5V and supports output currents up to 30mA per channel. It features a high-frequency switching topology at 940kHz, achieving efficiency up to 90%. The IC includes an integrated 40V power MOSFET and offers mixed-mode dimming capabilities.
Feature Summary
- Integrates a 40V power MOSFET and six independent current sinks for simplified circuit design
- Supports programmable mixed-mode dimming combining analog and PWM control methods
- Includes comprehensive protection mechanisms such as LED open/short detection and cycle-by-cycle inductor current limiting
Applications
- Tablet backlight systems
- Netbook and notebook display backlighting
- Portable media player LCD panels
Procurement Notes
Verify the specific suffix EFJ against the manufacturer datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the required operating temperature range of -40°C to +85°C. Confirm that the 1MHz switching frequency aligns with your inductor selection constraints. Validate pinout alignment if replacing existing designs.
Selection Notes
Select this component when driving medium-to-large LCD panels requiring high-efficiency boost conversion from single-cell lithium-ion batteries or 5V supplies. The integrated MOSFET reduces external component count compared to discrete solutions. Consider the 0.5% typical current matching specification for uniform brightness requirements across multiple LED strings.
Part Context
This part belongs to the KTD3156 family of LED drivers from Kinetic Technologies. These devices are engineered specifically for portable electronics where space and efficiency are critical. The family utilizes advanced current sink technology to ensure consistent LED performance across varying thermal conditions and input voltages.
Replacement Considerations
Direct substitutes may include other 6-channel boost LED drivers with similar 40V ratings and 30mA per channel output. Verify that alternative parts support the same 10S6P LED configuration and mixed-mode dimming interface. Check for compatible TQFN33-16 or WLCSP-16 packaging options.
