LT3508IFE#PBF

Overview

The LT3508IFE#PBF is a dual-channel synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.7V to 36V and provides two independently adjustable positive outputs, each capable of delivering up to 1.4A. The device features a fixed switching frequency between 920kHz and 1.06MHz. It supports an output voltage range from 0.8V to 35.28V. The component is housed in a 16-lead TSSOP package with an exposed thermal pad, designed for surface-mount installation.

Feature Summary

Dual independent channel architecture providing separate regulated outputs
Integrated high-side and low-side power switches for efficient operation
Fixed-frequency current mode control for stable transient response
Thermal pad design facilitating heat dissipation in compact layouts

Applications

Portable electronics requiring multiple voltage rails
Industrial equipment power distribution systems
Embedded computing modules with mixed voltage requirements
Automotive infotainment and control unit power supplies

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Ensure that the procurement channel sources components directly from authorized distributors to guarantee authenticity. Cross-reference the manufacturer part number with the latest datasheet revision history to validate manufacturing date codes and material declarations prior to finalizing orders.

Selection Notes

Select this component when designing circuits requiring two isolated DC-DC outputs from a single high-voltage source. The fixed switching frequency simplifies electromagnetic interference filtering compared to variable frequency alternatives. Evaluate the thermal performance requirements based on the load current and ambient conditions, as the exposed pad must be properly connected to the PCB ground plane for adequate heat removal during continuous operation.

Part Context

This part belongs to the LT3508 family of dual synchronous buck regulators. It shares architectural similarities with other Analog Devices power management ICs but is distinct in its dual-output capability and specific input voltage range. The device complements single-channel regulators like the LT3506 by offering integrated dual-rail generation without requiring external controller complexity.
