Controller IC Chip - MOSFET RT6543AGQW RT6543A ML= chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0895)
High Efficiency Single Synchronous Buck PWM Controller for INTEL VCCIN AUX ICL and TGL
The RT6543A/B PWM controller provides high efficiency, excellent transient response, and high DC output accuracy for stepping down high voltage batteries to generate low voltage CPU core, I/O, and chipset RAM. The RT6543A/B supports on chip voltage programming function between 0V and 1.8V by controlling VID1/VID0 inputs. Compared with conventional current-mode PWMs, the RT6543A/B achieves high efficiency WITHOUT any current sensing resistors. Furthermore, the RT6543A/B has ability to drive synchronous rectifier MOSFETs and enters diode emulation mode at light load condition that also save lots of power consumption. Besides, the RT6543A/B equips with UVLO, OVP, UVP, OTP and current limit protection. All above functions are integrated in a WQFN-20L-3x3 package.
