DC DC Switching Controllers datasheet and documents for LTC1772BIS6#TRPBF

LTC1772BIS6#TRPBF

DC DC Switching Controllers Overview

The LTC1772BIS6#TRPBF is a constant frequency current mode step-down DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.5 V to 9.8 V and supports output voltages from 800 mV to 9.8 V. The device delivers up to 5 A of output current with a fixed switching frequency of 550 kHz. It features a low quiescent current of 270 uA and functions reliably across an operating temperature range of -40°C to +85°C. Packaged in a TSOT-23-6 surface-mount case, it utilizes a PWM architecture to drive external power MOSFETs.

DC DC Switching Controllers Feature Summary

Employs a constant frequency current mode control architecture for stable regulation
Supports multiple topologies including buck, boost, and flyback configurations
Features a wide input voltage range suitable for single or dual cell battery applications

DC DC Switching Controllers Applications

Cell phones and portable electronics powered by Li-Ion cells
Systems operating from NiCd battery packs
General purpose step-down DC/DC converter designs

DC DC Switching Controllers Procurement Notes

Verify the specific suffix IS6 against official datasheets to confirm package type and temperature grade. Confirm RoHS compliance status through manufacturer documentation. Check availability as distribution channels may list limited stock or special orders. Ensure the ordering part number matches the required tape and reel packaging format.

DC DC Switching Controllers Selection Notes

Select this component when a compact solution is required for driving external P-channel MOSFETs in buck applications. Consider the 550 kHz switching frequency for balancing efficiency and component size. Evaluate the 270 uA quiescent current for battery-powered systems requiring low standby consumption. Verify that the external component selection supports the specified 5 A output capability.

DC DC Switching Controllers Part Context

This part belongs to the LTC1772 family of switching controllers designed for high-performance power supplies. It shares architectural similarities with other Linear Technology regulators but is distinct in its specific pinout and electrical parameters. The TSOT-23-6 package allows for minimal board space usage compared to larger industrial packages.
