LTC3788IUH#PBF

DC DC Switching Controllers Overview

The LTC3788IUH#PBF is a dual-phase, dual-output synchronous boost controller manufactured by Analog Devices Inc. It operates with an input voltage range of 2.5 V to 38 V and supports output voltages from 1.2 V to 60 V. The device features a programmable switching frequency between 105 kHz and 760 kHz. It includes integrated current sense amplifiers for both phases, eliminating the need for external resistors in many applications. The controller provides precise load regulation of 0.01% and operates within a junction temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Dual-phase architecture enables interleaved operation to reduce input and output ripple currents while improving transient response.
• Integrated high-side and low-side gate drivers support synchronous rectification for enhanced efficiency across wide load ranges.
• Built-in current sense amplifiers allow direct connection to external MOSFETs without requiring external current sensing resistors.

DC DC Switching Controllers Applications

• High-power industrial equipment power supplies
• Telecommunications infrastructure systems
• Point-of-load conversion stages

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the IUH package designation matches the required 32-pin QFN footprint for PCB layout compatibility. Ensure the operating temperature grade aligns with the intended thermal environment of the final assembly.

DC DC Switching Controllers Selection Notes

Select this component when dual independent outputs are required from a single boost topology. Consider the wide input voltage capability for battery-powered or variable source applications. Evaluate the maximum switching frequency limit against electromagnetic interference requirements and magnetic component selection constraints.

DC DC Switching Controllers Part Context

This part belongs to the LTC3788 family of synchronous boost controllers. Variants such as the LTC3788EUH differ primarily in package type and temperature rating. The series is designed for applications demanding high efficiency and tight regulation in step-up configurations.

DC DC Switching Controllers Replacement Considerations

LTC3788IUH#TRPBF offers identical electrical specifications but utilizes tape-and-reel packaging instead of tube packaging for automated assembly processes.
