LT3692AHFE#PBF

Overview

The LT3692AHFE#PBF is a dual current mode PWM step-down DC/DC converter featuring two internal 3.8A switches. It accepts an input voltage range of 3V to 36V and provides adjustable output voltages from 0.8V to 34.2V with a maximum output current of 3.5A per channel. The device operates at a switching frequency of 2.5MHz and supports a quiescent current of 630µA in shutdown. It is housed in a 38-pin TSSOP-EP package and functions within a temperature range of -40°C to +125°C.

Feature Summary

Dual independent channels simplify complex power supply tracking and sequencing requirements through dedicated control pins.
Each channel includes independent input voltage, shutdown, feedback, soft-start, UVLO current limit, and comparator pins.
Integrated 3.8A internal switches support high-efficiency synchronous buck conversion.

Applications

Dual-stage step-down converters for generating 5V and 1.8V outputs
Step-down converters with startup current limiting for 12V to 3.3V and 2.5V rails
Single-output configurations with UVLO/OVLO and power good status for 3.3V/5A loads
Quad-output multi-frequency synchronized converters for 5V, 2.5V, 1.8V, and 1.2V systems

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm exact electrical characteristics and automotive qualification status. Ensure the ordering part number matches the required pinout and thermal pad configuration for the 38-pin TSSOP-EP package. Cross-reference datasheet revisions to validate operating temperature ranges and switching frequencies before integration.

Selection Notes

Select this component when designing systems requiring two independent regulated rails with precise tracking or sequencing capabilities. The dual-channel architecture reduces board space compared to discrete solutions. Verify that the 3.8A switch current rating meets peak load demands and that the 2.5MHz frequency aligns with EMI constraints and passive component size requirements.

Part Context

This device belongs to the LT3692A series of monolithic dual tracking switching regulators manufactured by Analog Devices. It is categorized under PMIC - Power Management ICs and Switching Voltage Regulators. The component is designed for applications needing compact, high-efficiency power solutions with flexible output configuration options.

Replacement Considerations

LT3692AEFE#PBF is a verified substitute within the same family offering identical functional specifications and pinout compatibility.

FAQ

How does the LT3692AHFE manage power supply sequencing?

It utilizes independent shutdown, feedback, and soft-start pins for each channel, allowing designers to implement complex tracking and sequencing requirements without external logic.
