LT8637EV#WPBF

Overview

The LT8637EV#WPBF is a synchronous step-down switching regulator from Analog Devices, featuring Silent Switcher technology to minimize radiated emissions. It supports an input voltage range of 2.8V to 42V and delivers up to 6A of output current. The device integrates high-side and low-side power MOSFETs in a compact LQFN-20 package. It operates with a programmable switching frequency between 200kHz and 3MHz. Key electrical specifications include a maximum output voltage of 42V, a minimum operating temperature of -40°C, and a maximum junction temperature of +125°C.

Feature Summary

Silent Switcher architecture for reduced electromagnetic interference
Integrated synchronous buck topology with internal power switches
Wide input voltage capability suitable for automotive and industrial sources
External compensation design for flexible loop stability

Applications

Automotive battery-powered systems
Industrial point-of-load regulation
Telecommunications infrastructure power supplies
General-purpose DC-DC conversion for embedded systems

Procurement Notes

Verify the specific suffix WPBF confirms the tape-and-reel packaging format required for automated assembly processes. Confirm that the LQFN-20 package variant matches the thermal and footprint requirements of the target PCB design. Ensure compatibility with the intended switching frequency settings before finalizing procurement orders.

Selection Notes

Select this component when high efficiency and low noise are critical in space-constrained designs. The wide input range accommodates varying supply conditions, while the adjustable frequency allows optimization for size or performance. Consider the external compensation requirement during schematic design to ensure stable operation across all load conditions.

Part Context

This part belongs to the LT863x family of Silent Switcher regulators, designed for applications requiring strict EMI limits without external shielding. It shares architectural similarities with other members like the LT8638 but offers specific current and pinout configurations tailored for compact form factors.
