LX7169

WWW.Microsemi .COM LX7169 ® 3A Step-Down Converter TM PRODUCTION DATASHEET DESCRIPTION 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 digital soft start. excellent dynamic load response. The LX7169 also provides a Power Good The operational input voltage range of LX7169 is from 3V to 5.5V. The SYNC function. The LX7169 is available in a 12L 3mm x 3.5mm DFN package. pin is tied low when not in use. A clock signal to this pin will synchronize the converter to an external source. In the shutdown mode, the IC’s current...
