WWW.Microsemi .COM LX13049 TM ® VREF @ 800mV, 1.25A, 1.0MHZ PWM PRODUCTION DATA SHEET DESCRIPTION The LX13049 operates as a Current The regulator is capable of providing an Mode PWM Buck regulator that output load current up to 1.25A and has switches to PFM mode under light no minimum load current requirement loads. The entire regulator function is for stable operation. Current limit implemented with only a few, low- senses on a cycle-by cycle basis to cost external components. protect the switch. Power conversion The LX13049 responds quickly to efficiency is maximized with PFM dynamic load changes using a high mode of operation and low regulator bandwidth error amplifier and internal quiescent current. compensation.
