LT3512EMS#PBF

Overview

The LT3512EMS#PBF is a monolithic high voltage isolated flyback converter manufactured by Analog Devices Inc. It is housed in a 16-lead MSOP package and designed for automotive applications. The device integrates the controller, power switch, and protection features required for efficient flyback topology operation. It supports an input voltage range of 36V to 75V, providing a regulated 5V output at up to 500mA. A dedicated bias winding ensures optimal efficiency across the operating range.

Feature Summary

Integrates high-voltage power switch and control logic for compact flyback designs
Includes internal protection mechanisms against overcurrent and thermal overload
Features a dedicated auxiliary winding pin for optimized biasing and efficiency

Applications

Automotive power supply systems requiring isolated outputs
High-voltage DC-DC conversion from battery or alternator sources
Industrial control modules needing galvanic isolation

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm that the MSOP-16 package matches your PCB footprint requirements. Ensure the supplier provides official datasheets to validate the component's automotive qualification status and operational temperature range specifications before integration.

Selection Notes

Select this component when designing isolated converters with input voltages between 36V and 75V. It is suitable for applications requiring moderate output currents around 500mA. Consider the need for an external transformer with a bias winding to maximize efficiency. Evaluate thermal management needs due to the integrated power switch within the small MSOP package.

Part Context

This part belongs to the LT3512 family of monolithic flyback converters. It shares architectural similarities with other high-voltage switching regulators but is distinct in its specific input range and integrated protection features. The EMS designation refers to the MSOP package variant, differentiating it from other package options within the same functional family.
