DC DC Switching Controllers datasheet and documents for LTC1438CG-ADJ#PBF

LTC1438CG-ADJ#PBF

DC DC Switching Controllers Overview

The LTC1438CG-ADJ#PBF is a dual high-efficiency, low-noise synchronous step-down switching regulator manufactured by Analog Devices. It features two independent buck converters in a 28-SSOP package. The device operates with an input voltage range of 3.5V to 30V and provides adjustable output voltages from 1.19V to 9V. It supports a switching frequency up to 400kHz and delivers an output current of 50mA per channel. The controller includes soft-start, enable, and power-on reset functions, operating within a temperature range of 0°C to +70°C.

DC DC Switching Controllers Feature Summary

Dual synchronous buck topology for independent power rail generation
Low noise design optimized for sensitive analog circuits
Integrated control features including soft-start and shutdown

DC DC Switching Controllers Applications

Portable battery-powered equipment requiring multiple voltage rails
Industrial control systems with mixed-signal requirements
Communication modules needing stable low-noise power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix and manufacturer designation upon ordering, as Analog Devices acquired Linear Technology. Confirm the 28-SSOP package availability and check for any recent product change notices regarding marking or material composition. Ensure the supply chain source is authorized to guarantee component authenticity and traceability.

DC DC Switching Controllers Selection Notes

Select this component when dual isolated buck outputs are required from a single mid-range input voltage. It is suitable for applications prioritizing low output noise over high current capacity. Consider the thermal performance in the SSOP package if ambient temperatures approach the upper limit of the specified operating range.

DC DC Switching Controllers Part Context

This part belongs to the LTC1438 family of dual synchronous regulators. It shares architectural similarities with the LTC1438IG-ADJ but differs in industrial/commercial temperature ratings and packaging variations. The series is designed for compact power management solutions where space efficiency and signal integrity are critical constraints.
