LT1933IDCB#TRMPBF

Overview

The LT1933IDCB#TRMPBF is a current mode PWM step-down DC/DC converter featuring an internal 0.75A power switch in a 6-lead SOT-23 package. It operates with a wide input voltage range of 3.6V to 36V and supports fixed frequency operation at 500kHz. The device provides adjustable output voltages down to 1.25V, includes cycle-by-cycle current limit protection, and features soft-start functionality to eliminate input current surge during startup.

Feature Summary

Integrates a 0.75A power switch within a compact 6-lead SOT-23 package for space-constrained designs.
Supports wide input voltage ranges suitable for unregulated wall transformers, industrial supplies, and automotive batteries.
Includes cycle-by-cycle current limit protection against shorted outputs and soft-start to manage inrush current.

Applications

Regulating power from unregulated wall transformers
Powering systems from 24V industrial supplies
Battery-powered applications requiring low shutdown current

Procurement Notes

Verify the exact suffix and tape/reel specifications against the manufacturer's latest datasheet before ordering. Confirm that the DFN or SOT-23 variant matches your PCB footprint requirements. Ensure compatibility with your target input voltage range and thermal management strategy for the specific load conditions.

Selection Notes

Select this component when a small form factor is critical due to its SOT-23 packaging. It is suitable for applications requiring a wide input voltage range up to 36V. Consider the internal 0.75A switch limit and 500kHz switching frequency when determining external inductor and capacitor values for ripple and transient response.

Part Context

This part belongs to the LT1933 family of high-efficiency step-down switching regulators. It is designed by Analog Devices (formerly Linear Technology) to provide a simple solution for converting higher voltages to lower logic or analog supply levels in portable and industrial equipment.
