LT8608HMSE#PBF

Overview

The LT8608HMSE#PBF is a synchronous step-down switching regulator manufactured by Analog Devices. It operates with an input voltage range of 3V to 42V and delivers up to 1.5A of continuous output current. The device features adjustable output voltage, starting from a minimum of 0.778V. Switching frequency is configurable between 200kHz and 2MHz. Quiescent current consumption is specified at 1.7µA during operation and drops to 2.5µA in standby. The component supports surface mount installation in a 10-MSOP package with exposed pad and functions within a junction temperature range of -40°C to +150°C.

Feature Summary

• Integrates high-speed synchronous rectification for efficient power conversion
• Utilizes Burst Mode operation to maintain high efficiency at low load currents while minimizing output ripple
• Incorporates peak current mode topology with internal compensation for stable transient response
• Includes programmable undervoltage lockout and power good flag signaling capabilities

Applications

• Point-of-load regulation for industrial equipment
• Power supply stages in battery-powered portable devices
• Embedded systems requiring compact DC/DC conversion
• General purpose voltage regulation in consumer electronics

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when reviewing procurement documents. Confirm that the MSOP-10 package variant matches the thermal requirements of the target application. Ensure compatibility with the required input voltage range before finalizing orders. Cross-reference the manufacturer datasheet for any recent design changes or lifecycle status updates.

Selection Notes

Select this regulator when a wide input voltage range up to 42V is required alongside moderate current delivery. Consider the 10-MSOP package size constraints against available PCB space. Evaluate the need for external clock synchronization if jitter reduction is critical. Assess thermal dissipation needs based on the expected load current and ambient operating conditions.

Part Context

This component belongs to the LT8608 series of monolithic step-down regulators. It shares architectural similarities with other high-efficiency buck converters from Analog Devices but distinguishes itself through its specific 42V input rating and 1.5A output capability. The series emphasizes compactness and low quiescent current for energy-sensitive applications.
