LTC3703HGN#PBF

DC DC Switching Controllers Overview

The LTC3703HGN#PBF is a high voltage synchronous switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4V to 100V and supports adjustable output voltages. The device utilizes current mode control architecture for rapid transient response. It features a programmable switching frequency ranging from 100kHz to 600kHz, allowing optimization for efficiency or component size. The controller includes integrated bootstrap diode and driver circuitry for external N-channel MOSFETs. It offers comprehensive protection features including overvoltage lockout, thermal shutdown, and cycle-by-cycle current limiting.

DC DC Switching Controllers Feature Summary

• Supports wide input voltage range up to 100V for telecom and industrial applications
• Integrates high-side and low-side gate drivers for external N-channel MOSFETs
• Provides programmable switching frequency for design flexibility
• Includes built-in soft-start and tracking capabilities

DC DC Switching Controllers Applications

• Telecommunications point-of-load regulation
• Industrial power supply systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix HGN indicates the commercial temperature grade and SSOP-28 package configuration against the official datasheet. Confirm RoHS compliance status and lead times through authorized distributors. Ensure ordering documentation matches the exact part number including the #PBF designation for lead-free packaging specifications.

DC DC Switching Controllers Selection Notes

Select this controller when designing buck converters requiring input voltages exceeding standard 60V limits. The 100V rating accommodates noisy automotive or telecom environments without additional clamping circuits. Consider the SSOP-28 package for moderate pin count requirements. Evaluate thermal performance based on expected load currents and ambient conditions.

DC DC Switching Controllers Part Context

This component belongs to the LTC3703 family of high-voltage synchronous step-down controllers. It shares architectural similarities with other Linear Technology regulators but distinguishes itself through its extended 100V input capability. The device complements lower voltage alternatives like the LTC3703-5 which is limited to 60V inputs.

DC DC Switching Controllers Replacement Considerations

LTC3703IGN#PBF serves as the industrial temperature grade equivalent with identical electrical characteristics but wider operating range.
