- Wide 4 V to 65 V input range for direct operation from 12 V, 24 V, 48 V, or automotive 60 V bus
- Adjustable output voltage from 0.8 V to 65 V covers a broad range of system supply requirements
- 500 mA output current with Burst Mode operation for high light-load efficiency in battery-managed systems
- Fixed 3.3 V and 5 V output versions also available for simplified BOM in standard-rail designs
- 16-pin MSOP package enabling compact high-voltage buck converter implementation with minimal external components
What is LTC3630EMSE#PBF used for?
The LTC3630EMSE#PBF is suited for industrial sensors, programmable logic controllers, and fieldbus nodes that operate from 24 V or 48 V rails and require an efficient step-down to 3.3 V, 5 V, or a custom analog voltage. Automotive subsystems, including dashboard electronics and telematics modules connected to a 12 V or 48 V vehicle bus, benefit from its wide input tolerance and Burst Mode efficiency at idle. Bench and portable test instruments also use it as a flexible adjustable supply rail where the output can be programmed over a wide range without changing hardware.

Frequently Asked Questions
What input voltage range does the LTC3630EMSE#PBF support, and can it operate from a 48 V industrial bus?
The LTC3630EMSE#PBF accepts input voltages from 4 V to 65 V, comfortably covering the 48 V nominal bus used in industrial automation and telecom systems. The 65 V maximum also provides headroom for 48 V bus transients and cold-crank automotive 42 V applications without requiring additional input protection.
How does the Burst Mode feature of the LTC3630EMSE#PBF improve efficiency at light loads?
In Burst Mode, the LTC3630EMSE#PBF skips switching cycles when the output capacitor holds sufficient charge, reducing switching frequency and gate-drive losses. This allows the converter to maintain high efficiency at load currents well below 500 mA, which is critical for battery-powered and always-on industrial systems where standby current determines battery life.
What is the adjustable output voltage range of the LTC3630EMSE#PBF, and how is it set?
The LTC3630EMSE#PBF can be adjusted from 0.8 V to 65 V via an external resistor divider from the output to the feedback pin, which is referenced to an internal 0.8 V reference. Fixed 3.3 V and 5 V variants are also available in the same package, so designers can choose between a single programmable device or dedicated fixed-output versions depending on BOM simplicity requirements.
What output current can the LTC3630EMSE#PBF deliver, and is that sufficient for powering an ARM Cortex-M microcontroller with peripherals?
The LTC3630EMSE#PBF provides up to 500 mA of continuous output current. An ARM Cortex-M4 microcontroller with active peripherals typically draws 50 mA to 200 mA from its 3.3 V rail. The 500 mA rating provides sufficient margin for the MCU core, flash memory, SRAM, GPIO loads, and communication interfaces without approaching the current limit.
