Key Features
- Wide 3.6 V to 36 V input range with 3.5 A output current capability covering industrial, automotive, and telecom supply voltages in a single step-down regulator
- 2.4 MHz switching frequency minimizing external passive component size and enabling compact, low-profile power supply designs on space-constrained PCBs
- Current-mode PWM control in a 10-pin MSOP-E package delivering fast transient response and precise current limiting with minimal BOM complexity
Applications
The LT3693EMSE#TRPBF is used in industrial automation power supplies, automotive accessory modules, and telecom equipment where a wide-input (3.6 V to 36 V), 3.5 A step-down regulator with 2.4 MHz switching is required. Its high switching frequency reduces the size of inductors and capacitors, making it ideal for compact, high-density DC-DC converter designs. Current-mode PWM control provides rapid load transient response suitable for powering sensitive analog and mixed-signal circuits in demanding applications.

Frequently Asked Questions
What is the input voltage range and output current capability of the LT3693EMSE#TRPBF?
The LT3693EMSE#TRPBF accepts input voltages from 3.6 V to 36 V and delivers up to 3.5 A output current. This wide input range makes it suitable for automotive, industrial, and telecom applications where supply rails vary widely or unregulated bus voltages are present.
Why does the 2.4 MHz switching frequency of LT3693EMSE#TRPBF benefit compact PCB designs?
At 2.4 MHz, the LT3693EMSE#TRPBF allows the use of smaller inductors and output capacitors compared to lower-frequency regulators operating at 300-600 kHz, reducing the overall PCB footprint significantly. This is particularly beneficial in space-constrained portable and embedded industrial designs.
What control topology does the LT3693EMSE#TRPBF use, and how does it improve load transient response?
The LT3693EMSE#TRPBF employs current-mode PWM control, which inherently provides cycle-by-cycle current limiting and faster load transient response than voltage-mode control. This makes it well suited for powering sensitive analog circuits, FPGAs, or DSPs that experience rapid load changes requiring tight output voltage regulation within millivolts.
