Includes internal frequency compensation to minimize external circuitry
Features built-in thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

Distributed power supply systems
Pre-regulators for linear regulators
Efficient standard buck converters

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' corresponds to the TO-220 ZIP7 through-hole package configuration. Confirm that the '-12' designation indicates the fixed 12 V output variant. Ensure compliance with RoHS directives if lead-free versions are required for the assembly process.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12 V output is required at up to 3 A with a high input voltage capability. Consider the TO-220 package for applications requiring robust thermal dissipation without additional heatsinking solutions. Evaluate the 150 kHz switching frequency against EMI constraints and inductor size requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2599 series of SIMPLE SWITCHER regulators. It shares architectural similarities with other members like the LM2596 and LM2598 but offers higher current capacity compared to the 1 A LM2598. It is designed for straightforward implementation in DC-DC conversion tasks.
