LED Driver IC datasheet and documents for LM3630ATMX
LED Driver IC Overview
The LM3630ATMX is a dual-output DC-DC boost LED driver IC manufactured by Texas Instruments. It operates within an input voltage range of 2.3V to 5.5V and provides a regulated output current of 28.5mA per channel. The device utilizes pulse-width modulation (PWM) for dimming control and integrates internal power switches. It is housed in a compact 12-DSBGA package measuring 1.64x1.24mm, designed for surface-mount installation with an operating temperature range of -40°C to 85°C.
LED Driver IC Feature Summary
- Integrates two independent high-efficiency boost converters for driving dual LED strings
- Supports PWM dimming for precise brightness control without color shift
- Features internal power switches to minimize external component count
- Operates from low supply voltages suitable for battery-powered applications
LED Driver IC Applications
- Backlighting for mobile phones and handheld devices
- LED illumination for portable consumer electronics

LED Driver IC Procurement Notes
Verify the specific suffix 'TMX' corresponds to the tape-and-reel packaging configuration when ordering. Confirm that the 12-DSBGA footprint matches the target PCB layout constraints. Ensure compatibility with RoHS3 standards if required by regional regulations. Cross-reference the manufacturer part number with distributor codes to avoid sourcing errors during procurement.
LED Driver IC Selection Notes
Select this component when designing circuits requiring dual-channel LED drive from a single boost converter topology. It is appropriate for space-constrained designs due to its small DSBGA package. Consider the 28.5mA output limit when determining LED string configurations. Verify that the input voltage source remains within the 2.3V to 5.5V operational window for stable regulation.
LED Driver IC Part Context
This part belongs to the LM3630 family of LED drivers from Texas Instruments. It is specifically engineered for backlight applications in portable devices. The device complements other TI lighting solutions by offering integrated boost conversion and PWM dimming capabilities in a minimal footprint.
LED Driver IC Replacement Considerations
Consult official substitution guides for pin-compatible alternatives within the same product family. Verify electrical parameters such as output current and input voltage ranges before swapping components.
