LM5176RHFT General Description

Featuring current-mode control in both buck and boost modes, the LM5176RHFT ensures superior load and line regulation. The switching frequency is easily programmable using an external resistor and can be synchronized to an external clock signal for further system integration. The device also includes a programmable soft-start function, as well as essential protection features such as cycle-by-cycle current limiting, input undervoltage lockout (UVLO), and output overvoltage protection (OVP)

Key Features

High efficiency synchronous buck regulator

Wide input voltage range of 4.5V to 65V

Adjustable output voltage from 0.8V to 65V

Integrated high-side and low-side MOSFETs

Switching frequency up to 1 MHz

Overcurrent protection, thermal shutdown, and input undervoltage lockout features

Application

Cost-effective power control
Robust industrial applications
Innovative power technology
