DC DC Switching Controllers datasheet and documents for LTC1929CG#PBF

LTC1929CG#PBF

DC DC Switching Controllers Overview

The LTC1929CG#PBF is a dual-phase synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4V to 36V and delivers a maximum output current of 3A per phase. The device utilizes current-mode control with pulse width modulation (PWM) technology. It features a phase-lockable fixed frequency operation adjustable between 150kHz and 300kHz. The component is housed in a 28-pin SSOP package and supports a very low dropout operation with up to 99% duty cycle.

DC DC Switching Controllers Feature Summary

Dual-phase single output controller architecture that reduces required input capacitance and power supply induced noise
Current mode control mechanism ensures precise current sharing between phases
OPTI-LOOP compensation improves transient response while maintaining ±1% output voltage accuracy
Includes true remote sensing differential amplifier for enhanced load regulation

DC DC Switching Controllers Applications

High efficiency point-of-load (POL) conversion systems
Industrial equipment requiring stable low-voltage power distribution
Telecommunications infrastructure power supplies
Embedded computing platforms needing multi-phase power management

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering. Confirm RoHS compliance status as some sources indicate non-compliance for certain variants. Ensure the SSOP-28 package matches your PCB footprint requirements. Check operating temperature limits against your environmental specifications before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring high efficiency and reduced input ripple through dual-phase interleaving. Consider the 4V to 36V input range suitability for various bus voltages. Evaluate the need for remote sensing if long trace lengths are present. Compare switching frequency options against EMI constraints and inductor size requirements.

DC DC Switching Controllers Part Context

This part belongs to the LTC1929 family of high-efficiency synchronous step-down regulators. It is designed to drive external N-channel MOSFETs in a two-phase configuration.
