LX7169 - 3A Step-Down Converter

General Description

KEY

Key Features

  • LX7169 is a step-down PWM Switching Other features of the part are: regulator IC with integrated high side P- a) Cycle-by-cycle current limit Channel and low side N-Channel followed by HICCUP mode which MOSFETs. The IC operates using a reduces the overall power dissipation of hysteretic control topology with a full load the internal MOSFETs operating frequency of 3MHz. This switching frequency allows for small output filter components while maintaining b) Thermal protection and internal.
