The LM2578AN from Texas Instruments is a flexible switching regulator designed for DC-to-DC voltage conversion applications, capable of buck and boost topologies. It operates from an input voltage range of 2V to 40V and provides an adjustable output voltage from 1V up to 36V, with a maximum output current of 750mA (0.75A).
Key features include an enable function, over-current protection, and thermal shutdown for robust operation. The device has a maximum duty cycle of 90% and a typical quiescent current of 2.5mA. It utilizes an internal 1.0V reference and supports both positive and negative output configurations.
This component is housed in an 8-pin PDIP package suitable for through-hole mounting. The operating temperature range is -40°C to 85°C (ambient). Its design flexibility makes it suitable for various power management circuits requiring efficient voltage regulation.
The LM2578AN is designed with separate inverting and non-inverting comparator inputs, simplifying circuit design and PCB layout. It also features an external current limit terminal for enhanced control.
