Controller IC Chip - RT8231BGQW RT8231B ( 3T=** ) QFN20 Chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0949) The RT8231A/B provides a complete power supply forDDR2/DDR3/DDR3L/LPDDR3/DDR4/LPDDR4 memorysystems.  It  integrates  a  synchronous  PWM  Buckcontroller with a 1.5A sink/source tracking linear regulatorand buffered low noise reference.The PWM controller provides the low quiescent current,high efficiency, excellent transient response, and high DCoutput accuracy needed for stepping down high-voltagebatteries to generate low-voltage chipset RAM suppliesin  notebook  computers.  The  constant  on-time  PWMcontrol scheme handles wide input/output voltage ratioswith ease and provides 100ns “instant-on” response toload  transients  while  maintaining  a  relatively  constantswitching frequency.The RT8231A/B achieves high efficiency at a reduced costby  eliminating  the  current-sense  resistor  found  intraditional  current  mode  PWMs.  Efficiency  is  furtherenhanc
