The UC2578DPTR from Texas Instruments is a Pulse Width Modulator (PWM) buck controller IC designed for step-down voltage regulation applications. It is capable of driving an external high-side NMOS switch and operates with an input voltage range of 14V to 72V. The device integrates a 100kHz internal oscillator, a 2V reference, and under-voltage lockout (UVLO) protection.
Key features include soft start on power-up and an overcurrent shutdown circuit followed by a soft start, providing robust protection during overload conditions. The output duty cycle can vary between 0% and 90%. This controller is suitable for distributed power systems and telecommunication bus voltages.
The UC2578DPTR is available in a 16-SOIC surface mount package. It operates within an industrial temperature range of -40°C to 85°C.
This part is classified as 'Not For New Designs', and a recommended substitute is the LM5088MHX-1/NOPB from Texas Instruments.
