Overview
The KTD3136EUS-TR is a high-efficiency three-channel LED driver IC utilizing a boost topology. It operates within an input voltage range of 2.7 V to 5.5 V and supports output voltages up to 32 V. The device provides three independent current sinks, each capable of delivering up to 30 mA. It functions at switching frequencies of 500 kHz or 1 MHz and includes PWM dimming capabilities. Packaged in a WLCSP-12 format, it is designed for applications requiring compact power management solutions.
Feature Summary
- Integrates three independent high-efficiency current sink channels for multi-string LED control
- Supports PWM dimming for precise brightness adjustment and visual flicker reduction
- Includes open LED protection mechanisms to ensure system reliability during fault conditions
Applications
- Backlight drivers for medium to large LCD panels
- Portable electronic devices powered by single-cell lithium-ion batteries
- Systems requiring 5V power supply regulation for LED arrays
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status directly with Kinetic Technologies before integration. Confirm that the WLCSP-12 package dimensions align with your PCB footprint requirements. Ensure your design accounts for the thermal characteristics associated with the specified operating temperature range of -40°C to +85°C.
Selection Notes
Select this component when designing circuits for LCD backlighting that require three separate LED strings driven from a low-voltage source. It is suitable for space-constrained portable electronics where high efficiency and small form factor are critical. Consider its compatibility with I2C interfaces if digital control is required for the dimming functions.
Part Context
This part belongs to the Kinetic Technologies KTD series of LED lighting drivers. These components are engineered specifically for display backlighting applications, offering integrated power switches and control logic to minimize external component count. The series focuses on providing reliable performance for mobile and consumer electronics markets.
Replacement Considerations
Consult official manufacturer substitution guides for verified equivalents. Cross-referencing requires matching the 3-channel boost architecture, WLCSP-12 package, and electrical specifications such as the 2.7V–5.5V input range and 30mA output current capability.
