TL2575HV-33QKTTRQ1 TI DC-DC Converter | TO-263 | 3.3V Fixed Output, 1A

Product Overview

The TL2575HV-33QKTTRQ1 from Texas Instruments is a high-voltage, step-down switching voltage regulator with a fixed 3.3V output. It is part of the TL2575HV series, designed to provide efficient power conversion for automotive and industrial applications. The device operates over a wide input voltage range from 4.75V to 60V, making it suitable for systems with unregulated power sources. With a maximum output current of 1A, it integrates a 52kHz fixed-frequency oscillator, internal compensation, and a high-side N-channel MOSFET. The TO-263 (DDPAK-5) package ensures excellent thermal performance and compact footprint.
