Overview
The TPS61140DRCTG4 is a dual-output boost converter IC from Texas Instruments, designed for LED lighting applications. It operates within an input voltage range of 2.5 V to 6 V and supports up to two independent outputs. The device integrates synchronous rectification and features a switching frequency of 1.2 MHz. It is housed in a 10-VSON (3x3 mm) package with a maximum duty cycle of 93%. The component supports PWM dimming and functions across an operating temperature range of -40°C to +85°C.
Feature Summary
- Dual output configuration with integrated single inductor topology
- Synchronous rectification for improved efficiency
- Supports PWM dimming control for brightness adjustment
Applications
- LED backlighting systems
- Portable electronic devices requiring dual voltage rails
- General LED lighting drivers
Procurement Notes
Verify the specific suffix 'G4' indicates RoHS compliance and lead-free status as per manufacturer standards. Confirm the package marking matches the 10-VSON form factor. Ensure the ordering part number aligns with the cut-tape variant rather than reel quantities if small volume procurement is required. Cross-reference the datasheet revision to ensure compatibility with current design specifications.
Selection Notes
Select this component when a compact dual-output solution is needed for low-voltage input sources. The 1.2 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the thermal performance within the 10-VSON package for high-current LED loads. Verify that the input voltage range of 2.5 V to 6 V matches the system power supply constraints.
Part Context
This part belongs to the TPS61140 family of dual-output boost converters. It shares architectural similarities with other TI LED driver ICs but is distinct in its dual-channel capability and specific 1.2 MHz switching frequency. The DRCTG4 designation specifies the tape-and-reel cut-tape packaging and environmental compliance.
Replacement Considerations
TPS61140DRCR is a compatible alternative with identical electrical characteristics but may differ in packaging quantity or specific manufacturing lot details. Verify pinout compatibility before substitution.
