LM20145QMHE/NOPB TI Power Management IC | 16-HTSSOP | 4.5V-42V Input, 1.5A Output

Product Overview

The LM20145QMHE/NOPB is a high-performance, automotive-grade step-down (buck) regulator from Texas Instruments. It operates over a wide input voltage range of 4.5V to 42V and delivers up to 1.5A of continuous output current. Housed in a compact 16-pin HTSSOP package with exposed pad for enhanced thermal performance, this device is designed for robust power management in demanding environments. Its integrated high-side and low-side MOSFETs, combined with a fixed 2.1MHz switching frequency, enable a small solution size while maintaining high efficiency. The device features a precision enable input, programmable soft-start, and a power-good flag for system sequencing. With built-in protection features including overcurrent, overtemperature, and undervoltage lockout, the LM20145QMHE/NOPB ensures reliable operation in automotive and industrial applications.
