Overview
The SC600BIMLTRT is a mAhXLife LED driver IC from Semtech, utilizing a fractional charge pump topology to provide regulated constant current output. It operates within an input voltage range of 2.5 V to 6.5 V and delivers a fixed 4.5 V output at 120 mA. The device functions at a switching frequency of 650 kHz and includes integrated short-circuit and over-temperature protection with soft-start functionality. Packaged in an MLPD-10 (3x3 mm) surface-mount format, it supports operation temperatures from -40°C to +85°C.
Feature Summary
- Inductorless fractional charge pump design reduces electromagnetic interference and component count
- Patented low noise mode switching circuitry enables use of extremely small capacitors
- Integrated protection mechanisms include short-circuit, over-temperature, and soft-start features
Applications
- LED backlighting for cellular phones
- Power supplies for PDAs and handheld computers
- Portable electronics and electronic books
- Wireless web appliances
Procurement Notes
Verify the specific output voltage and current rating against the datasheet, as the SC600 series includes variants with different configurations such as 5.0V/60mA or 4.0V/120mA. Confirm package type compatibility and ensure the selected revision matches the required thermal and electrical specifications for the target application environment.
Selection Notes
Select this component when designing compact battery-powered systems requiring high efficiency without inductors. The MLPD-10 package suits space-constrained layouts. Ensure input voltage stability aligns with Li-ion battery discharge curves and verify that the 650 kHz frequency fits EMI constraints relative to nearby sensitive circuits.
Part Context
Part of the Semtech mAhXLife family, designed for portable devices needing efficient power conversion. The SC600 series replaces traditional inductive boost converters with a switched-capacitor approach, offering comparable efficiency in a smaller footprint suitable for mobile consumer electronics.
Replacement Considerations
Direct substitutes within the SC600 family include SC600AIMLTRT (5.0V output) and SC600CIMLTRT (4.0V output). Verify pinout and functional equivalence before substitution.
