LTC3736EGN-1#PBF

DC DC Switching Controllers Overview

The LTC3736EGN-1#PBF is a synchronous step-down switching controller manufactured by Analog Devices Inc. It features a dual-phase buck topology with an input voltage range of 2.75 V to 9.8 V and adjustable output voltages from 600 mV to 9.8 V. The device supports up to 5 A output current per phase and operates at a fixed switching frequency of 750 kHz. Key electrical specifications include a quiescent current of 9 uA, a supply current of 500 uA, and a load regulation of 0.12%. It is housed in a 24-lead SSOP package and functions within a temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Integrates two synchronized buck controllers for high-current applications without requiring sense resistors.
• Provides precise output tracking capabilities between the two regulated channels.
• Includes a dedicated soft-start pin to manage inrush current during power-up sequences.

DC DC Switching Controllers Applications

DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix matches the required package and temperature grade. Request original manufacturer documentation to validate lot traceability and RoHS compliance status before finalizing acquisition.

DC DC Switching Controllers Selection Notes

Select this controller when designing systems requiring dual independent outputs from a single input source. Ensure the external MOSFETs can handle the peak currents associated with the 5 A per phase rating. Verify that the PCB layout accommodates the SSOP-24 footprint and thermal requirements for continuous operation.

DC DC Switching Controllers Part Context

This component belongs to the LTC3736 family of no-RSENSE synchronous buck controllers. It is designed to simplify power design by eliminating current sense resistors while maintaining high efficiency. The EG-1 variant specifies the commercial/industrial temperature range and specific package configuration.

DC DC Switching Controllers Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully to ensure compatibility with existing circuit designs.
