LT1619EMS8#PBF

Overview

The LT1619EMS8#PBF is a low voltage current mode PWM controller manufactured by Analog Devices Inc. It operates with input voltages up to 18V and provides an output current of 1.5A. The device functions at a fixed frequency of 300kHz, designed for implementing DC/DC converters with minimal external components.

Feature Summary

Low voltage current mode PWM control architecture
Fixed frequency operation for simplified design
Optimized for minimum external component count

Applications

Current mode DC/DC converter implementation
Low voltage power supply designs
Power management IC applications

Procurement Notes

Verify the manufacturer designation as Analog Devices Inc. or Linear Technology depending on the specific datasheet version. Confirm the package type is MSOP-8 and the suffix #PBF indicates lead-free compliance. Ensure the operating voltage range matches the 18V maximum specification for your circuit requirements.

Selection Notes

Select this component when a fixed frequency current mode controller is required for low voltage applications. It is suitable for designs needing an 18V input limit and 1.5A output capability. Consider the 300kHz switching frequency for inductor selection and efficiency trade-offs compared to higher frequency alternatives.

Part Context

This part belongs to the LT1619 series of power management controllers from Analog Devices. It is closely related to the LT1618 series but differs in specific control parameters and packaging. The EMS8#PBF designation identifies the surface mount MSOP-8 package variant within this product line.

Replacement Considerations

LT1618EMS8#PBF is a related component in the same family. Verify functional compatibility regarding switching frequency and control topology before substitution.
