Overview
The LT1618EMS#TRPBF is a constant-current/constant-voltage step-up DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 1.6 V to 18 V and delivers an adjustable output voltage from 1.263 V to 36 V. The device utilizes a fixed 1.4 MHz switching frequency and features a current-mode control architecture. It is housed in a 10-lead MSOP package with a thermal pad, designed for efficient power conversion in space-constrained applications.
Feature Summary
- Combines traditional voltage feedback with unique current feedback loops for precise regulation
- Supports both constant-current and constant-voltage operation modes simultaneously
- Enables the use of compact, thin inductors and capacitors due to high switching frequency
- Features adjustable current limit via the IADJ pin with a standard 50 mV detection threshold
Applications
- LED backlight drivers requiring precise current regulation
- USB-powered boost or SEPIC converters
- Input current-limited boost or SEPIC converters
- Battery charger ICs
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging rather than tube packaging when sourcing. Confirm the manufacturer is Analog Devices Inc., formerly Linear Technology. Ensure the component matches the 10-lead MSOP physical dimensions. Cross-reference the datasheet revision date to confirm technical specifications remain consistent with your design requirements.
Selection Notes
Select this component when designing systems that require simultaneous constant-current and constant-voltage outputs from a single stage. It is suitable for applications needing wide input voltage ranges up to 18 V. Consider the 1.4 MHz frequency for minimizing passive component size. Verify that the required output voltage does not exceed the 36 V maximum limit specified in the electrical characteristics.
Part Context
This part belongs to the LT1618 family of micropower switching regulators. It is distinct from other LT series converters by its dual-loop feedback capability specifically optimized for LED driving and battery charging. The EMS variant denotes the MSOP package, differentiating it from DFN package options within the same functional family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative Analog Devices boost converters with similar 1.4 MHz frequencies and MSOP-10 packages if direct substitution is required.
