What are the key features of LTC3632EDD#TRPBF?
- 4.5 V to 50 V wide input voltage range supports direct regulation from 12 V, 24 V, and 48 V industrial and automotive supply rails without a pre-regulator
- Adjustable output voltage from 0.8 V to 50 V using a single external resistor divider provides maximum design flexibility for low-voltage microcontroller and logic supply rails
- Hysteretic current-mode control delivers fast transient response and inherently stable regulation without external frequency compensation components
- High-efficiency synchronous step-down topology with 20 mA output current capability suits low-power bias supply and housekeeping regulator applications in industrial equipment
What is LTC3632EDD#TRPBF used for?
The LTC3632EDD#TRPBF is designed as a bias supply or housekeeping regulator in industrial control systems, building automation equipment, and automotive modules where the main supply rail ranges from 12 V to 48 V and a regulated low-voltage output of 1.8 V to 5 V is needed for microcontrollers, communication ICs, or sensors. Its 50 V input rating and 20 mA output make it ideal for powering isolated gate driver supply rails, CAN transceiver bias circuits, and EEPROM supply rails derived directly from high-voltage bus. The hysteretic control architecture ensures stable operation without external compensation, simplifying PCB design in space-constrained power management sections.

Frequently Asked Questions
What is the input voltage range of the LTC3632EDD#TRPBF and which supply rail environments does it support?
The LTC3632EDD#TRPBF operates from 4.5 V to 50 V input, covering 12 V automotive, 24 V industrial, and 48 V Power-over-Ethernet and telecom supply rails. This wide range allows direct connection to the main bus in industrial PLCs and motor drive control cards without an intermediate pre-regulation stage.
How is the output voltage set on the LTC3632EDD#TRPBF and what is the minimum achievable output?
The output voltage of the LTC3632EDD#TRPBF is set by an external resistor divider connected to the feedback pin, with the internal reference voltage at 0.8 V. This allows adjustment from 0.8 V up to 50 V output, enabling generation of 1.2 V, 1.8 V, 2.5 V, or 3.3 V rails for microcontrollers, DDR memory bias, and logic circuits from a single 24 V or 48 V bus.
What control mode does the LTC3632EDD#TRPBF use and how does it simplify the surrounding circuit design?
The LTC3632EDD#TRPBF uses hysteretic current-mode control, which is inherently stable without an external type-II or type-III compensation network. This eliminates the 3 to 5 external frequency compensation components typically needed by voltage-mode or average current-mode controllers, reducing BOM count and simplifying loop stability verification across the 4.5 V to 50 V input range.
For which housekeeping power applications is the LTC3632EDD#TRPBF well-suited given its 20 mA current capability?
The 20 mA output current of the LTC3632EDD#TRPBF is well-matched to bias supply applications such as powering isolated gate driver ICs (typically 5 mA to 15 mA quiescent), CAN or RS-485 transceivers (3 mA to 10 mA), EEPROM or flash memory chips, and reference voltage circuits in industrial sensor modules operating from a 24 V or 48 V main bus.
