LTC1142HVCG#PBF

DC DC Switching Controllers Overview

The LTC1142HVCG#PBF is a dual high-efficiency synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates within an input voltage range of 3.5 V to 20 V and delivers up to 700 mA output current per channel. The device features adjustable output voltages, a fixed switching frequency of 250 kHz, and low static current consumption of 160 µA. Packaged in a 28-lead SSOP, it supports operation from 0°C to +70°C.

DC DC Switching Controllers Feature Summary

• Dual synchronous buck topology for independent or combined outputs
• Automatic Burst Mode operation for enhanced light-load efficiency
• Integrated high-side and low-side drivers for external MOSFETs

DC DC Switching Controllers Applications

• High-efficiency notebook power supplies
• Battery-powered portable equipment
• Industrial control systems requiring dual regulated rails

DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm RoHS compliance status via the official datasheet. Check current availability as supply may be limited. Ensure ordering suffix matches required package and temperature grade specifications before purchase.

DC DC Switching Controllers Selection Notes

Select this controller when dual isolated or non-isolated buck conversions are needed from a single input source. Consider thermal management requirements for the SSOP package at full load. Verify external component compatibility with the 250 kHz switching frequency and drive strength capabilities.

DC DC Switching Controllers Part Context

Part of the LTC1142 family of dual synchronous regulators. Designed for applications requiring two efficient step-down converters in a compact footprint. Complements other PMIC solutions by providing discrete control flexibility for custom voltage rails.

DC DC Switching Controllers Replacement Considerations

LTC1142HVCG-ADJ#PBF is a variant with adjustable output configuration. Cross-reference with LTC1142HVCG#TRPBF for tape-and-reel packaging options. Verify pinout compatibility before substitution.
