LTC3703HGN#TRPBF

DC DC Switching Controllers Overview

The LTC3703HGN#TRPBF is a synchronous step-down switching regulator controller from Analog Devices, designed for high-voltage applications. It supports input voltages up to 100V and provides an adjustable output voltage range of 800mV to 24V with a maximum output current capability of 20A. The device operates within a switch frequency range of 100kHz to 600kHz and features a low quiescent supply current of 1.7mA. It is housed in a 16-SSOP package and functions reliably across an operating temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Supports direct step-down conversion from input voltages up to 100V
• Integrated synchronous rectifier control for high efficiency
• Adjustable switching frequency allows optimization for size and performance

DC DC Switching Controllers Applications

• Telecommunications power systems
• Industrial point-of-load regulation
• High-voltage battery-powered equipment

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the H-grade variant meets the required 100V input specification compared to lower voltage variants. Ensure the 16-SSOP footprint matches the PCB layout design. Cross-reference the manufacturer's latest datasheet for any pinout or electrical characteristic updates prior to final procurement.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring high input voltage tolerance without external level shifting. The integrated synchronous drive reduces external component count. Compare against the LTC3703EGN#TRPBF if the application does not require the extended 100V input range, as it may offer different thermal characteristics. Ensure the chosen switching frequency aligns with inductor saturation requirements.

DC DC Switching Controllers Part Context

This part belongs to the LTC3703 family of synchronous buck controllers. It shares functional similarities with the LTC3703IG-5#PBF but differs in package type and specific voltage ratings. The HGN suffix denotes the high-voltage version in SSOP packaging, distinguishing it from the standard EG or IG variants found in other listings.
