DC DC Switching Controllers datasheet and documents for LTC1622IS8#TRPBF

LTC1622IS8#TRPBF

DC DC Switching Controllers Overview

The LTC1622IS8#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 V to 9.8 V and provides an adjustable output voltage with a maximum output current of 5 A. The device features a fixed switching frequency of 550 kHz and a typical quiescent current of 350 uA, dropping to 270 uA during operation. It supports shutdown functionality and offers excellent AC and DC load and line regulation. The component is housed in an SOIC-8 package and is rated for operation between 0°C and +70°C.

DC DC Switching Controllers Feature Summary

Constant frequency current mode control architecture for stable regulation
Integrated synchronous rectifier driver eliminating external clock synchronization needs
Shutdown pin capability for power management efficiency

DC DC Switching Controllers Applications

Portable battery-powered equipment requiring efficient step-down conversion
Industrial systems utilizing 5V or 3.3V distribution networks
Post-regulation stages for higher voltage bus architectures

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the industrial temperature grade (I-grade) matches application requirements against commercial variants. Ensure compatibility with external MOSFETs selected for the 5 A current rating and 550 kHz switching frequency. Validate that the SOIC-8 footprint aligns with the PCB layout design specifications.

DC DC Switching Controllers Selection Notes

Select this controller for designs prioritizing high efficiency in low-to-medium power buck applications. It is suitable where external clock synchronization is unnecessary due to integrated synchronous drive. Consider the 2 V minimum input voltage for single-cell lithium battery operation. Evaluate thermal performance based on the SOIC-8 package limitations under full 5 A load conditions.

DC DC Switching Controllers Part Context

This component belongs to the LTC1622 family of micropower switching regulators. It serves as a core power management IC for converting higher input voltages to lower regulated levels. The IS8 designation specifies the industrial temperature range and SOIC-8 package variant within the broader product line.
