LTC3803ES6-5#TRMPBF

DC DC Switching Controllers Overview

The LTC3803ES6-5#TRMPBF is a constant frequency current mode flyback DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 5.7V to 75V and provides a fixed 5V output. The device supports up to 1A output current with a switching frequency of 200kHz. It features low static current consumption of 240uA and functions reliably across a temperature range of -40°C to +125°C. Packaged in a TSOT-23-6 surface-mount case, it includes shutdown capability and precise load regulation.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRMPBF confirms the tape and reel packaging format and lead-free status. Confirm the ES6 grade matches your thermal requirements. Ensure compatibility with your PCB footprint for the TSOT-23-6 package. Cross-reference the datasheet revision date against your design timeline.

DC DC Switching Controllers Selection Notes

Select this component when a fixed 5V isolated output is required from a wide input range up to 75V. The 200kHz frequency balances size and efficiency. Consider the TSOT-23-6 package constraints for thermal dissipation at full load. Verify that the non-synchronous topology meets your efficiency targets compared to synchronous alternatives.

DC DC Switching Controllers Part Context

This part belongs to the LTC3803 family of flyback controllers designed for compact isolated power solutions. The ES6 variant denotes the extended industrial temperature range. The IS6 counterpart offers similar functionality but may differ in temperature grading or testing standards. These controllers are intended for space-constrained designs requiring reliable isolated conversion.
