TL3844DR

DC DC Switching Controllers Overview

The TL3844DR is a current-mode PWM controller manufactured by Texas Instruments, designed for DC/DC switching applications. It supports Boost, Flyback, and Forward topologies with a single positive output configuration. The device operates within a supply voltage range of 10V to 30V and features a maximum switching frequency of 500kHz. It provides a maximum duty cycle of 50% and delivers an output drive current of 1A. The component functions reliably across an operating temperature range of 0°C to +70°C and is housed in an SOIC-14 surface-mount package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'DR' corresponds to the SOIC-14 tape-and-reel packaging variant when sourcing. Confirm that the commercial temperature grade (0°C to +70°C) aligns with system requirements, as industrial variants may exist under different part numbers. Ensure compatibility with the 10V to 30V Vcc supply range during design validation.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring a robust current-mode controller with a 1A output drive capability. The SOIC-14 package facilitates surface-mount assembly. Consider the 500kHz switching frequency limit when designing magnetic components. Verify that the 50% maximum duty cycle constraint meets the input-to-output voltage ratio requirements of the target topology.
